Several OKW call in infantry were actually used quite a lot, pre OKW rework, mostly due to scaling.
-Falls were niche but the epitome of glasscannon (merit on them for been able to rival Obers)
-JLI was favoured by certain top players in some metas
-PF were basically 7man Conscripts with SVT for OKW
SP has been the only one who was always in a weird spot as it mostly cause issue by been strong as an opening unit but seeing later diminishing results.
OKW rework basically threw everything out of the windows by reducing scaling and every single one of them saw rework later on.
When you consider "main line power creep" is because you are missing the whole forest behind it.
Cons late game were always bad (except whenever PPSH was OP) because everything else would pick up the slack. You can have "BAD" conscripts because everything else in the game will wipe. Remove everything that wipes and now you have "bad conscripts". Also free/5 muni oorah, cheaper molos, indestructible sandbag spam and flares.
Grens could be "glascannons" because they were facing SU only. Bring USF and UKF into the mix and you have issues. Specially after you remove the equivalent cheese they had when facing SU initially.
Saying Rifles were buffed because they got a slight DPS increase at close range while they also lost something as powerful as smoke on main line infantry (which also debuffed vehicles). As well as Officers no longer starting with BAR and Zook (for all that it matters, they remain to be another Rifle squad).

I agree. Still some points:
-I started playing competitive multiplayer late 2017. The time before that I mostly played against bots with intervals of not playing CoH2 at all in between. I remember Oorah being free at some point, but I do not have a coherent memory of the meta and general state of the game at that time because against bots you can still win if you're a total scrub and have no idea about the units and abilities. So whatever I say starts from very late 2017/early 2018 onwards.
-Falls, SP and JLI are not mainline infantry. When JLI became OP and 3 squads could wipe anything off the field they were nerfed out of this role again. PF as far as I remember did not work very well, but then again I did not play them that much.
-If something is considered a power creep or not is basically completely arbitrary. Most units were OP and UP at some point of the game and got nerfed and buffed. Set your reference point before the buff and you suddenly get "power creep".
I don't think it makes much sense anymore to compare the game now to the CoH2 close to release. The game was quite different back then from what I remember, even against bots. I think a 1-2 year span comparison makes sense, since the general game style has not changed drastically, yet we have enough patches in between to see the game develop and potential overbuffs or -nerfs corrected with future updates.
