Just as soon as I get another spare disk. BTW anyone can try that, so the
call goes to the Mac users in general.

The user can still name the partition anything (s)he wants as long as LVM
is part of the name.

Too bad really. Suppose a french user is even unhappy with the Linux_Swap
type setting. Same thing. With respect to computers, broken english
is lingua franca.

Which does this, so unstable parted we shouldn't bother about?

I don't care if it has super cow powers. You can't count on the partition
table to be created by Linux tools, much less parted.

So who is the LVM tools maintainer, and which committee do we have to
address this across distros?
