How would it stop working?  I guess I don't see the problem; can you
describe it?

Yes.  But AFAIU the suggestion to "add blockers" simply makes these
functions wait until the process is in that state.  So code that did
this outside of those functions will "just work" because these
blockers will become no-ops.

No, I don't think so.
