I don't think so: I think PDX wanted to try to change things that are too essential. As I told, there was this game that had no limits in recruiting troops and everyone ended up having huge armies, to make you understand one with a number of states equal to 10 in Europe, could recruit a bigger army than China, USSR and USA put together and fielded with TWO Dockyard (REPEAT TWO! 2!) A naval fleet larger than the US and UK combined. And all because there was no army limit given by maintenance. Let me be clear in Hoi4 the Manpower redoes VERY slowly and this "blocks" a little ... but not much. From my experience in the videogame field, the army limit (and ships and planes therefore included) serves not only for realism or to avoid lag, but for balance. If tomorrow you take Eu4, remove the gold upkeep, you get the result that the AI spams troops as if there was no tomorrow, instead if you also see the gameplay, you see that a large part of the budget is absorbed by military expenses (including fortresses) followed (usually) by the colonies and missionaries.Problem is, the fix in the earlier games of hoi would not serve hoi4 well which has evolved to a different game.
The army is mainly a cost! And that's that! In MMOs you can smooth out the cost of the army by stealing resources from the enemy (as on Ck2 and Ck3 you do with the Vikings: D) but the army is mainly for defending yourself (basic) and waging offensive wars (to conquer industries and resources on Hoi4 and therefore "pays for itself like this").
