Military Engineers can speed up districts for Aztec

[Infixo]

As Monty, I can use not only Builders, but also a Military Engineer to speed up districts.
Can't find any info about that on Wiki, so - is it a bug or some feature I missed?
I enclose 2 screenshots (before and after), to show that this is not an UI glitch, it really adds production to the district.

Is there any reason you want to do that, though?

I discoverd this while testing how AI plays games. Monty just builds tons of them. So, the problem is that it most likely hurts him a lot.

So Monty districts cost are 425 prod at most. Seems interesting when builders cost more than 500 prod each.

I thought the builders use charges, not themselves … it might still be worth if a builder has many charges or for production/gold/faith rerouting. (to smaller cities e.g.)
