D&D 5E (2024) Homunculus Servant, Conjure Constructs, Deryan's Helpful Homunculi have class restrictions that make no sense

BG3 has a lot of (implied) artificers, even though the class isn’t implemented for PCs.

And the high priest of Gond is the High Artificer. Most of his worshippers are inventors who are definitely Artificers, even if not called that explicitly.

Wizards need to keep their filthy hands off other classes' pets. Seriously, they don't wash hands after ruffling through that lich's tome. Gross.

Until they learn proper hygiene and to properly care for their own familiar, they get no more spells or subclasses.

Yeah its very much entrenched that Artificers are in the Forgotten Realms (and by way of FR, Ravenloft, Planescape, and Spelljammer).

Yep. - Artificers fit in pretty much all current D&D settings.
I would not be surprised if the class is reprinted in a later "of Everything" book, probably with an updated spell list.
