IMHO - disagree but it depends on point of view so this is not ”you are wrong” but ”in my view it’s not like that”.

I think it’s the role of the software vendor to offer a package for a modern platform.

Not the role of OS vendor to support infinite legacy tail.

I don’t personally ever need generational program binary compatibility. What I generally want is data compatibility.

I don’t want to operate on my data with decades old packages.

My point of view is either you innovate or offer backward compatibility. I much prefer forward thinking innovation with clear data migration path rather than having binary compatibility.

If I want 100% reproducible computing I think viable options are open source or super stable vendors - and in the latter case one can license the latest build. Or using Windows which mostly _does_ support backward binaries and I agree it is not a useless feature.
