I hear you on this, but is the VM really your only hope?

If you were programming in C wouldn’t you grab some C header
file and ask a function in there somewhere?  And if that’s the
case surely there is a way to spin up a Panama FFM access to
the same API.  Or is that already one of Uwe’s “too hacky”
solutions?
