I agree that this should be fixed, but I wonder whether this is entirely
new in v19.

AFAICS, the same kind of misleading "removable" count can also occur with
CLUSTER USING INDEX in v18 and older releases, since the count depends
on the scan path. The CONCURRENTLY case is new, but the USING INDEX
case does not seem to be.

So I'm not sure this should be considered a v19 blocker. Perhaps
documenting this limitation for now would be sufficient?
