SMTV does though, it just lowers the experience outside of the main party
Which actually touches on another big point imo, which is that Pokemon by default is a 1v1 system, as opposed to the 4vX of the games you mentioned. Which means without EXP share you're only leveling one Pokemon at a time, as opposed to 4 party members
The best comparison imo is protagonist Personas, and having just finished P4G recently I can confirm that not having EXP share there (not counting Growth skills) feels pretty bad. Especially compared to its sister series
