Thanks for chiming in.

Test harnesses frequently need to jump through various hoops,
certainly so when they need to mock-out some APIs to do their job.

I don't think I understand: the output of that function depends on
native-comp-eln-load-path, so why tweaking that is not enough?

If those can help you solve your problem, I think that's "good enough"
for something that needs to be done in a test suite.  My primary
target audience, in contrast, is Emacs users.

A similar solution could have solved your problem even if
inhibit-automatic-native-compilation didn't exist at all,and we only
had comp-enable-subr-trampolines and native-comp-deferred-compilation,
right?

Why do you need this to be done together with disabling native
compilation? why not do it with two separate settings?

I understand the convenience, but once again, my primary audience is
the Emacs users, and they rarely need to handle such convoluted
situations.  Some relative inconvenience aside, I see no reason why
you couldn't make do without the environment variable, but via some
automatically-loaded init files or somesuch.

Thanks.
