Not a direct reply, but:
If you have a copy of "The Camel Book", otherwise known as "Programming
Perl" by Larry Wall, Tom Christiansen & John Orwant" pub. O'reilly, or
know somebody who has a copy, have a read of Chapter 5 'Pattern
Matching' which contains about the clearest explanation of how regexes
work and how to write them that I've seen anywhere - and better yet, it
describes Perl regexes, which is what SA uses.
FWIW there are also C and Java regex dialects, which are not at all
useful in SA rules.
https://www.regular-expressions.info/ is also useful.
Its worth knowing about these too:
https://www.regexplanet.com/advanced/java/index.html
https://regex101.com/
They are both pages for testing regexes: both let you type in a regex
plus test strings to check whether the regex does what you expect - or
not!

The CHAOS.pm module has an eval: from_no_vowels that may do the job as
well. Like most of the stuff in there it has internationalization so
that vowels in other language character sets are taken into account.
This looks at the From Name field.
