Agreed! Oddly none of the 'techie' lists I have ever been on enable this 
feature. Couple of critter lists that started on Listserve and moved to 
Mailman do. First learned of Mailman back in 2001 when one of then switched 
to 2.0.6. 

BTW do not see a "Keywords: header." but do see an X-Topics: FOO. With FOO: 
also appearing in the Subject header.
