Can we limit this somehow? Or split it up? Which part of this is "fix
new BOOST features, not ever even executed without BOOST", and which
part of this is "fixes core stuff"?

I *really* hate the timing of this. The code that is only impacted by
BOOST I cannot find it in myself to care about, and I'd be willing to
consider it basically EXPERIMENTAL and just pulling it.

IOW, is the core non-boost fix just a few obvious oneliners?

The "it all broke completely" in previous version of this also doesn't
make me get all the warm fuzzies. Which all makes me go "what is
minimal and really really SAFE?"
