Not so fast please, Adrian. At the risk of sounding harsh, non-release
old ports like powerpc *really* don't get to dictate things in Debian
But booting old machines is still desirable for GRUB. Is there a reason why HFS is actively bad for modern machines? Especially if it's disabled in case of lockdown.
Can I have more details about your security concerns? I may consider rewriting parts of HFS code to improve it. 

As Daniel Axtens has been finding out, the HFS code is terrible in
terms of security. If you still need it for old/semi-dead machines,
maybe you should fork an older grub release and stay with that?
