I run emacs in a server environment under different users regularly, and
I consider this a drawback.

As soon as I discovered NATIVE_FULL_AOT, I've been using it. JIT is
nice, but it's relatively easy to trigger. Even if that's async, it's
quite noticeable.

I personally prefer to pay the AOT price in disk space just from a
latency perspective. Which is actually a space saving anyway, in a
multiuser system.

And speaking of opinions, I'd also wish the eln-cache would be stored in
an opportune xdg path when an xdg config is being used ;)
