Yeah I'd be fine if they add it on Steam after the game gets finished. I just hope they do it because it's the only way I can buy the game
If Deimus had made a game using the classic Ren'Py approach—just text and images—it would have been feasible to publish on Steam long ago. But this game is practically a cartoon, so the usual strategy doesn't work.
As for accessibility due to Patreon blocking... The best option is to use the build of the game published here: although the plot is a bit behind the beta version, it has full localization and minimal bugs. But for some reason, everyone wants the beta version, with its bugs and broken localization :-)
