FWIW, I also would _not_ have expected compatibility between contrib
and core.   In fact, I would have expected contrib tsearch to be a
place where experimental APIs existed and that the single
biggest difference between contrib vs core was that the
core APIs removed any cruft that might have been in contrib.

If default_text_search_config makes things more confusing or more
fragile, I'd rather see it gone than kept around for
backward-compatibility-to-pre-core reasons.
