For now we don't see the value of it, no. Steam doesn't work well with on-going development games as they forbid you to have an updated version behind a paywall even if temporary. (Some creator don't respect that, but they are in fact in breach of Steamwork TOS)
It would only work with a finished version, which is not something we are anytime soon close of.
How does uploading the most up-to-date build on Steam (that you have to pay for/own the game) infringe on the ToS though? It's the same as it would be here... the free version is the demo version, and the full version is the one you buy. Except you only pay once and "own" the license for all future builds, I guess.
" Except you only pay once and "own" the license for all future builds, I guess."
That's the big difference. It would be like paying one time on Steam and never pay again for having the update "in advance". I don't think it would neither feel fair for the sub on SStar/Patreon, nor it would be fair if i put the game on steam with a big price to compensate.
I just don't see either of this happening, unless we do some sort of Deluxe edition that we never make free after the game is finished. And even then it would have to wait that the game is finished.
