At least regarding homebrew PlayStation games, for me that was a very valuable grey area space on the PSP and then PSVita, since back then there weren't many other kid-friendly options for similar portable computers (this being relevant because as an adult I am not dependent on convincing someone else to buy me things).

Nowadays smartphones are so much more capable and so much more accessible to kids, plus you can even get literal handheld PCs like the Steam Deck, so homebrew is a lot less worthwhile in my opinion (except for just the sake of hacking, since consoles at least tended to have very interesting security/DRM arrangements).
