I think you might be overestimating how much it actually matters (performs).
Last time I checked it was a few percent at best which on i386 only hardware
most likely wont matter at all in the end. It's very likely not to make your
H.264 1080p clip play smoothly etc and keep in mind that for the majority of
this ports lifetime LTO hasn't even been enabled or for that matter available.
See

(added in Dec of 2019)

I very much welcome "free" performance enhancements and if someone wants to
investigate it that's great but it's probably not worth adding to the pile of
"things to investigate do with very limited resources".
