I think you probably want a separate hook just for this purpose, rather than 
repurposing ts_record_change. We could have a lower-level 
after-change-functions that is immune to with-silent-modifications. Whether we 
should add such hook is probably another discussion. (So I opened a new 
thread.) I think it will be handy, but I don’t know that problem it might cause.
