Forget syntax tables: did you know that 'downcase' and
case-insensitive string match uses the current buffer's
case-conversion table?
IOW, the issue you raise is not the only place in Emacs where
buffer-local settings can change the results. In many use cases,
using buffer-local settings is what the Lisp code wants; if not, it's
the responsibility of the caller to set up things differently.
