If there is a one unit per tile limitation, then it would require that a single unit can lose a battle and not die unless VERY heavily out-gunned. That or at least a removal of the automatic movement into a tile after defeating an enemy. Otherwise a battle line is too hard to maintain with the requirement to move new units in to position to fortify a breach.
Mostly, it would MASSIVELY increase micromanagement, unless you can select units from multiple tiles at the same time and give them persistent orders (try to get to tile X, if occupied, wait till it isn't).
Can you imagine having to shuffle units through a chokepoint in the middle of your land if there is a 1 unit limit? Worker is trying to build a pasture, but Horseman needs through, so move the worker to the side, move the horse in, move the horse past, move the worker back, re-order building. Now warrior needs through, move the worker aside, move the warrior in, move the warrior past, move the worker in....
HOWEVER! If "one unit" meant "All units on the stack act communally for attack/defense" then you get more of a "Combined Arms" warfare approach. You still bring in multiple units, and can bring them out one at a time. But there is no selection of the "best defender" involved, and when you attack someone else with overwhelming force (20 tanks) you aren't held at bay because they have swarms alone (2,000 scouts)
