That does prevent having a pattern {a, b} where where a should be
matched as a literal string and b should be matched as a string
pattern.

It might, but again, these row flags tend to limit
expressiveness--e.g. having a pattern {a, b} where a is matched fully
and b is matched partially, or having a pattern that fully matches the
array part of a table but ignores other fields in the table.

Yes, although a similar thing may be needed for the hash-portion.
