globs make sense for file system operations, and we've been using them for decades in shells. I think globs make less sense for header value pattern matching.
Looking at my sieve/procmail recipes, I rarely use globs (except in blacklisting), it seems.
In the blacklisting case, it's against words in Subject: lines, as well as Sender:/From: headers. I'd imagine (for those still using such things), that's a fairly common approach.
