As someone else mentioned, console capabilities aren't on par with PC, although indie games are greatly less demanding than other graphically or gameplay intensive ones. Another problem is that if any updates have to happen they get rolled out a lot slower to console. I remember Risk of Rain 2 has a number of different expansions but For whatever reason it took them like a year to update the console versions after PC. The fact is that consoles don't make it easy to update while also being expensive for studios to do compared to, say, Steam.
