That sounds like a clever workaround.

There's been quite a bit of discussion on fixing this properly.  See,
for example
id:"CAH-f9WsPj=1Eu=g3sOePJgCTBFs6HrLdLq18xMEnJ8aZ00yCEg at mail.gmail.com".
The gist is that we need to include message IDs (or document IDs) in
the search output and use these in tagging operations, rather than the
unstable thread:XXX queries.  Unfortunately, actually fixing this got
stalled since adding this information the text format is a fool's
errand (having been the fool, I can say this!), so we need to switch
Emacs over to using the JSON search format first.  However, once
that's done, it's a relatively simple change.
