One of the reasons Steam held out for so long was that a lot of the games they host are 32-bit only. Games are built by a company, many of which have gone belly-up, so rebuilding the game from scratch is impossible. Making Steam 32 bit even though it could be 64 bit is a really effective way to guarantee a large chunk of their legacy products will still run. In a lot of ways, because of the nature of the gaming industry, Steam has it worse than most package managers/app stores.



Remember that the portion of Steam users that use Proton regularly is less than 10%, if you include Deck users. That number is rising and is probably a major factor in the decision to switch, but it’s still a minority.
