Trampolines are needed for any native-compiled function which
gets redefined.  We could try to build them eagerly when the
native-compiled function is compiled, and there could be various other
ways to handle this.  There's room for improvement here, but the current
system works well enough for a first version.

While I was going over the archives for answers to my questions (following Eli's 
observation), I found these gems:
https://lists.gnu.org/archive/html/emacs-devel/2021-02/msg00599.html
https://lists.gnu.org/archive/html/emacs-devel/2021-02/msg00724.html

I have the impression these ideas/concerns got lost in all the other work required
to get the first release ready, but I could have missed a follow-up definitively knocking
them down.
