They don't need to test two architectures, if there is only 32-bit. So that's not a real point. And CPU extensions for a basically shop? Alright the Steam app is not just a store, that's true, but it's not like a game or low level library itself. So I am not sure if additional 64-bit only CPU extensions is a great reason.
I'm not convinced at the moment that this is a huge win. The biggest reason is being dependent on the older libraries, which in some environments is just nasty. I am also not against 64-bit only. It is just surprising how much demanding some users are and how hugely celebrated this is, if it actually doesn't matter much in real world. As said, besides the library thing.
With windows 11 not supporting 32 bit the librarys will slowly start become stale and more work would need to be done to upgrade or patch issues that arise. In theory any program should be forward compatible but steam is still active and needs to be a moving target. but what would be the point supporting an architecture that the os isn't even supporting.
That is not what i was asking. I'm not negative here (if it sounds like). Besides supporting legacy old 32 bit libraries, are there reasons why someone want to go 64-bit only?
Some bug and issues only appear on 32-bit architectures, so you do have to test for both. Which is a strain, for only such a amall userbase.
