Allowing both --name and --uuid for the same functionality would be
nicer, is there a reason why we can't do that?

--uuid show UUIDs without title.
Guessing it's used for scripts?

Jan already provided a review. I agree with his view. Allowing both
--name --uuid is better than the new argument.

Hi,
My only concern is that why we forbid --uuid with --name at the same time at the
begining.
If we let them come together, does that bring some backcompat issues?

Hi,

you can research the history rather easily using gitk... I suggest
looking at commit id '419e5fb3' which implemented the --uuid and --name
switches and the commit message gives you more details.
In addition to what's already been posted - you're adding UUID but
making it an exclusive of optTitle, but I see no check for that. What if
someone wanted both?
Another way to "think" about this is that "by default" there are 3
items
displayed. Historically, if someone uses --uuid, then only uuid's are
displayed. Likewise, if someone uses --name, then only name's are
displayed. Over time, we allowed --title to mean default (or optTable
in the code) plus title.
So now you're proposing to allow displaying the UUID. Since it's not a
"default" output, you can choose where/how to place it. Of course your
proposal can bring out various opinions - my would probably keep Name
and UUID closer together. UUID is at least "sized" so that helps with
columnar output.
Perhaps using the VSH_EXCLUSIVE* macros may help you devise a way to
print out perhaps what someone wants. I don't think it would be
difficult to allow the default, but then allow someone to supply other
column names as switches to allow an "ordered" display of data (eg,
virsh --id --name, displays id and name. virsh --name --uuid --state
displays name, uuid, and state).
