While I take your point, I'll note that a Harfbuzz update doesn't seem
to meet any of the criteria required for backports: it is more of a
convenience for maintainers. We could take the view that because
Harfbuzz is not part of the core OpenJDK but is a separate library we
don't have to be so strict, I suppose. But such a change must be
reviewed and discussed in the usual way.

Let's investigate which targets will be adversely affected by this
change, and make a decision based on what we find. I have been
wondering for some time about building Vanillas with a more recent
version of GCC but still using the old libc for compatibility (as
Oracle do AFAIAA) and maybe this is the time to put that idea into
effect.
