I just realized those only affects some terms.

parameter works: https://docs.python.org/3/glossary.html#term-parameter

And LBYL does work but only if LBYL was used: https://docs.python.org/3/glossary.html#term-LBYL

The EAFP term does link to #term-LBYL instead of the old #term-lbyl.

It looks like the capitalization changed. The search doesn't seem to know that though (the LBYL glossary link at the top is broken): https://docs.python.org/3/search.html?q=lbyl

I would vote for changing the link back to lowercase rather than changing the search to link to the new URL. Otherwise links to specific glossary terms scattered around the internet will all link to the top of the glossary page instead.
