they talked about it a while back (im so srry i totally forgot what post this was from, wondering if anyone else has it//can link it) but they basically said the homestable customization was paused indefinitely, and that it was way too big of a project to take on at the time, mentioning how there'd be way too many bugs and it would essentially be a shotty//unfinished feature.
it is unfortunate, not only are we stuck with two items that cant be used (paint and couch) but it would have added so much personality to each person's individual homestable. the "invite friends to stable" feature would be way more popular, too.
