I ran into this unannounced change:

I noticed this is categorized as self-contained, which I think is wrong.

I also have hardware that would no longer run Fedora after such change
(a netbook with an older Intel Atom CPU which supports SSE2, but is
32bit). Unless the change proponent can provide some numbers suggesting
that 32bit users are a tiny minority of our userbase, I'll probably
be against such change.

Anyone with 32-bit hardware is going to be against this change.
Well, many 32-bit intels support SSE2. Original i686ers don't.

That said, I am against this step.

 It is
a known downside.  It also doesn't change the fact that i686 kernels
are in a zombie state, where the kernel team does not actively support
them and the community has not significantly stepped up to do so.
That approach was done quite a while ago, and explicitly communicated.
This was a step, anybody with 32bit HW should have being against.

And in deed, I have always considered this decision to be management and leadership mistake.

The fact that i686 kernels continue to work in general is basically luck.
You probably will deny this, but in practice it has been so for many years, because the i686 has dropped out of RHAT's business interest.
