That's right, but new hardware, that I wish to use with the old machines might
not because of no backporting of new drivers. Same goes for new software
utilising newer kernel features.

Those mentioned by Chris Friesen, whose arguments you apparently ignored.
Going back to your original arguments:

No. X32 is merely yet another ABI supported by Linux.

Perhaps. But that would rather be because of low benefits offered by x32 (not

You are allowed to compile most of the software running on Linux yourself. If
you want a binary to use the x32 ABI, go compile.

No. If kernel.org runs out of diskspace, I'd rather sponsor some new disks.
And, x32 is an ABI for the x86-64 architecture, while x86-32 is an
architecture in itself.

No. If, for instance, an m68k maintainer/developer stops maintaining m68k
support, nobody is telling him to continue his works on, say, sparc or
whatever hyped architecture.
In other words: It costs exactly *nothing* for us to have x86-32 support. What
is does cost, though, is the maintainers/developers spare time and goodwill.
Something we all should appreciate.

No. That plan will come automagically when x86-32 is not used anymore and when
somebody works on a patch to remove x86-32 support.
