So you're telling me that Valve should create a new branch of the existing steam client using an alternative browser engine explicitly due to dropped support on a platform that (I would argue) less than a fraction of a percent would use in 2025 and beyond? Along with maintenance, security patches (on an OS that will never receive any new official patches for current vulnerabilities) and feature parity for at least the steam library?

If you're that dependent on hardware/software combinations so far removed from the current development status quo, you should have the technical expertise to install DRM-free games on your obsolete OS that should never be online anyway.

I don't think anyone at the company nor customers with even a modicum of understanding of software maintenance would endorse that. It would be a gross waste of engineering time and resources. Hell, explaining this to you in such detail should be lesson enough on why software companies filter user suggestions.

You joke but most of the CPUs released in 2005 were 64 bit. That's why I'm curious about what the original commenter is trying to run Steam on.
