In 1700 less than 2 percent of New England's inhabitants were slaves ... Europe in 18th century ...
The game is not just about New England and it is not just about 17th or even 18th century.

The time frame of 15th and 16th century and also other colonial regions were much less civilized.
The change from white slaves-for-limited-time to mostly black permanent-slaves
The "white slaves-for-limited-time" still existed for the jobs that were less worse, than the jobs blacks were forced to do as slaves.
Especially in the less urban regions there was a huge gap between people that owned property and land and people that did not.
The true number of people that were "indentured" is not known officially because often it was not even with an official contract.
In regions that were hardly civilized land owners could basically do whatever they wanted with the poor land workers they had hired.
Also e.g. dock workers and other hard labour jobs for e.g. building railroads often were done with low paid contracts over e.g. 2 years - sometimes just being fired when done.
Some people were simply so poor that they just had to accept such contracts - they may not have been called "Indentured Servants" but in reality they were nothing else.

Narrowing down colonial history just to the things that sound romantic just serves to clean wash current generations to feel better.
Also arguing about if those people were officially called "Indentured Servants" or basically just lived under the same social circumstances helps nobody.
Not all social injustice commited in the New World was done to Natives and Africans.
Some of it was also done to Whites by other Whites - even though it might have been less brutal.

For me the
"Indentured Servant" in this game is not necessarily a person who signed a contract to sail on a Ship to the colonies.
It is more or less
just the poor Colonists that had much lower social status and rights - thus easily being exploited by society.
So are we really going to argue that this class of poor and exploited people did not exist?
Or are we now really going to argue that these "several year low paid contracts" did not exist?
Or are we really going to argue that they were free to chose whatever life they wanted - basically starve or accept those contracts?
Or are we really going to argue that poverty and social discrimation of a family did not impact the chances of their children?

Yes, the lives of these "poor people", often having to beome "indentured" to survive can not be compared to the misery of the actual slaves.
But still they were a social class of themselves living a life that was far from being truly free or equal or having the means to easily escape their conditions.

Summary:
We often tend to think in a very simplistic way of
just "black and white", "free or slave" ... which is a way of thinking I do not like.
There is
a lot of grey in this world as well ... and sometimes this grey is also
pretty dark already ... and thus should sometimes also be talked about.
In a mod that tries to be
"realistic",
"immersive" and
"complex" I think we should try to also have some grey.
Meaning
not to give the impression that everybody born in the Colonies was "equal, free and rich" - because that was simply not the case.
----
If necessary to end this discussion we can also simply
rename the
"Indentured Servant" to
"Poor Labour Worker".

(Personally however I consider this unnecessary because basically it was almost one and the same in those days.)
Being poor simply meant you had to hire for very bad and low paid jobs often also being forced to sign very long running contracts.
(They would range from 1 year to 5 years usually. And if you were not wealthy enough at the end you had to do the same again.)
