That appears to ignore what these tables are actually used for. They
are used for Unicode normalization, which is used by SCRAM. So in a
slightly hyperbolic sense, keeping these tables updated is
security-relevant. They are also used by psql to determine character
width and format output correctly.
Building a collation provider on this came much later. It was possibly
a mistake how that was done.
