In what way is this less of a concern?

That's true in some cases, but not in all of them.  And the dialog is
not really relevant here: the issue I raise is with the concept of
incremental searching being unfamiliar.

Some applications added incremental search, but many don't have it,
and probably never will.  Simple editors are in that class.

Improving the (non-existing) search dialog is a separate discussion.
If you want to work on such a dialog, please do.  but that is not what
we are talking here.  The proposal on the table is to remove
non-incremental search commands from the Search menu.  let's stay
focused on that issue, okay?

No, I think this is fundamentally a search command.  TAGS is just an
aid.

What kind of workaround do you have in mind?

There's something new to learn about Emacs every day ;-)

I don't mind, if this will really help this to be more discoverable.
(Of course Xah Lee thinks that our Help menu is too large as it is...)
