Not necessary, really, I think.  Pretty much every
time "flag" is used it's accompanied by "deletion".
(Extra emphasis, I imagine.)

Necessary?  No.  What's necessary, besides read,
eval, print?  Someone thought it was helpful.
Probably someone who was worried about users
accidentally deleting files.  Maybe the same
someone who implemented prompting for deletion
confirmation.

> Does it really need to be that complicated,

Is it really complicated?  As one user, I don't
think so.  But YMMV.

Someone thought so.  I agree with whoever that
was.  But I'm just one user, like you.

I don't think anyone said there's anything wrong
with that.  But in that case, there's also no
reason to introduce two different terms - just
"mark" with different "marks".

It's fine with me if everyone wants to remove mention
of "flag" and "flagging".  If you do that, please do
it well, everywhere.  Say explicitly which marks are
involved for each action, unless an action applies to
all marks.

If you make such a change, it's not just a fix for
this minor bug.  You'll need to adjust text, menus,
etc. everywhere, to be consistent.

(IMHO, there's no need in that case to also change
function and variable names.  Ideally, yes, if use of
"flag" is removed then Dired functions and vars with
"flag" in their name should be renamed.  Similarly, but
with less importance, functions and vars with "mark" in
their name should ideally be renamed if they affect
only certain marks - to say that.  But I wouldn't ask
for any such renamings, personally.)

My only position here has been to say what the Dired
convention is and has always been.  And to say that
I think it should be respected consistently.  Any
inconsistencies are candidates for correction.

The convention doesn't come from me.  I'm just the
messenger, reminding us about it.  As a user who knows
it, I've benefitted from it (when I see "flag" I know
it's about deletion).  But I won't argue that the
convention can't be changed.

If someone proposes to change the convention, e.g. to
remove any mention of "flag", then please do that
consistently.  That's all.
