It's not that I don't feel like allowing that for personal
reasons. It's rather that doing so is inherently unsafe in
PostgreSQL, eg child tables' keys WILL NOT GET UPDATED by it.

Generally: If you update rows in a parent table directly those
updates WILL NOT show up in the corresponding child tables.
This is a severe limitation in PostgreSQL's inheritance
support.
