tags-loop-continue is also used by Dired, see 'A' and 'Q' in
"Operating on Files".

Look at this from the user's POV: these two commands, as well as
tags-search and tags-query-replace, are still available, so users will
expect to be able to continue them as they did before.  How can we
explain to them that the keybinding for that command changed?

Other than that, what technical solution is used to keep the command
and its keybinding available is unimportant, I think.
