What is the lexical/syntactic structure of these region IDs? Can/do we assert
the correct structure somewhere in the browser process?

There is no lexical/syntactic structure, these are arbitrary website provided
strings. At your suggestion these methods already do a basic sanity check to
make sure the size of these strings is < 200.
