Because why not? It had the best 5th gen ports to begin with. The real question is when someone will port Monkey Ball to the system.

Coders typically aren't artists. Artists would rather make their quirky esoteric LSD Dream Emulator ripoff in a coderlet-friendly engine like Godot or Unity than go through the trouble of working with a programmer that can make his PS1-inspired indie game work on real hardware. It's why most homebrew projects have shitty programmer art.
Even on the Dreamcast where homebrew engines or SDKs are available, they require significant programming knowledge to use unlike a lot of the boilerplate game engines of today. Until the Dreamcast gets something like GB Studio, you'll probably not see a lot of indie games on the discontinued platform. Up to you if you think this is a good thing or not.

I assume its because the PS2 has thousands of games already unlike the Dreamcast, which was put out of production very early on the market so there's a lot of "what could've been" energy.
Its probably why you don't see a lot of homebrew games being made for the Wii, a lot of the manpower was focused on piracy. (Not a bad thing, mind you.)
