Is it time to dump disklabel and use GPT instead?

I am relatively certain nobody is going to argue, your points are
mostly valid, and there are others you did not mention.

I am also relatively certain nobody is going to stand up and do the
work, unless you do. There is finite manpower and to my knowledge
existing committers have any number of priorities before even
considering GPT.

Failing this it is possible someone would make it a priority if there
were a reasonable code bounty placed on it.
