Thanks.  I consider these weak reasons, so it doesn't look a very
urgent issue, especially since running etags on all the files in a
tree is not a very wise thing to do anyway (as mentioned in
http://lists.gnu.org/archive/html/emacs-devel/2018-01/msg00383.html).

However, feel free to file a feature request on debbugs, the
implementation shouldn't be hard.
