Yes, I understand what you are saying.

OK, but why?
What I'm missing so far is an explanation on why we shouldn't use sudo for
this use-case.

Following the Unix philosophy of using a collection of specialized small
tools that do one thing best, when performing an action as another user it
seems to be the correct thing to use a tool that "execute a command as
another user" rather than one whose primary goal is "change user ID or
become superuser"
I would be in complete agreement to not use that tool if it was either new
or obscure, but I don't think this can be said of sudo.
Should I ask the -devel mailing list to help us get out of our confusion?
Have a great start of your week.
