I don't think I understand what you mean by "fragile".  It is slower,
but otherwise is stable and reliable.

If you don't have libgccjit installed, the default build will not
enable native compilation.  As libgccjit is an optional part of GCC
installation, people who don't care about native compilation should
not be bothered by this default (if we decide to make it the default).

If the above is the only problem, I see no reason to reject the
proposal based on it alone, since the solution is easy and in most
cases effortless.  On the contrary, people who do want native
compilation should invest some effort into installing libgccjit that
matches their GCC version.
