This is now my opinion, too.
Regrettably the code has some history of stop-and-go development.
I added features when Vladimir requested them. And now i cannot
remember all the motivations.

But it is surely no inadverted change. At worst it was a decision
which has some drawbacks.

of course as we have precedent we cannot simply go and set it now.

We could create an option in xorriso and in grub-mkrescue
by which the user can override the automatic decision.
Like --mark-mbr-part-bootable $part_number
(or shorter :)).

Well, I don't think that it will work for my use case (creating an iso that works on all platforms, including broken UEFI platforms that check non-bootability of the 0xee partition and broken BIOS platforms that check that at least one bootable partition exists in the MBR).

In other words, without the ability to create a hybrid MBR (like gdisk does) or remove GPT, this flag would be useless.
