We are talking about mainline here, there's no support for suspend
blockers, so nothing is dropped.

In the mind of everybody, suspend blockers is for opportunistic
suspend, which only makes sense on sensible hw (not current x86). So
in the mind of everybody, x86 should be out of scope for the analysis
of suspend blockers.

Are you seriously suggesting that one of the strong arguments in favor
of suspend blockers is x86 usage (nobody agrees)? If not, then drop
it.

If I enable suspend blockers on my laptop, I have to modify my
user-space. Otherwise my system will behave horribly.
