I don't know. Could it be that the regexp was just made as
conservative as possible?

What about the `binding correction' BCOR, which has existed in
KOMA-Script for as long as I know:

\documentclass[a4paper,BCOR8.25mm]{scrreprt}

This example is taken straight from the KOMA-Script manual
scrguien.pdf, dated 2007-01-09.

I'd say the period has to be allowed in AUCTeX, because it is `valid
LaTeX', as it seems.
