 Would it be possible to add a more user-friendly way to present this
to the user?

Maybe a special command to toggle the PMBR bootable flag while looking
at the GPT?  That would make the complexity / existence of the PMBR more
discoverable for users, because it would show up in the built-in help
command output while looking at the GPT.  Toggling bootable is just
about the only useful thing you can do with the PMBR on a GPT disk,
and by far the most common, so "hiding" that functionality / status when
looking at the bootability of GPT isn't ideal.

That's pretty non-obvious.  I don't think many people would come up
with that on their own if they aren't partitioning / sfdisk experts.
Of course it makes a good recipe, so hopefully people will find it
with google.
