I wouldn't call standard rules with a slightly reduced set of pieces a variant really. Especially if you start from an easily possible/plausible position, its just training for certain types of position so an entirely logical method to improve play in those circumstances.
Now if you take it further then yes you get a variant.
Actually there's a rather notable historical one with white having 8 extra pawns but no Q. Due to Legal as per the Enclyopedia of chess variants. Apparently rather balanced and played a fair bit back in the day. (Labourdonnais, Deschapelles etc). Where the extra pawns (free choice 3rd/4th ranks) start seems to matter quite a bit.
There's a fun extremist version from Bezta with black having 7 knights and 16 pawns vs a normal army. Extra pawns seemingly fixed at b5-g5,c6,f6 here - their placement will make again make quite a difference.
I've not played that specifically but do know its wonderfully fun coordinating pawn/knight masses like that. Thats from playing something similar with fairy pieces, fairly free selection of armies etc.
Its certainly fun to see how say more Shogi pawns do vs fewer western ones. Or how various knight/camel (3,1 leaper) things do in practice. Once ~Queen alternative I did like was bishop + knight + camel all in one piece. Terrifying mobility of course, but somehow limited too. Or knight/(non royal) king crosses. Or a bunch of shogi step movers or....
But good for my chess? Nah. Just fun
(Computer print outs onto flat pieces cf Western shogi pieces kept it entirely playable.).
Although I guess a sense of perspective cf other entirely worthwhile games existing might be somehow useful. Shogi/Chinese chess/Go etc great for that too of course. Or even Bridge
