...and is described as dangerous, can cause message loss in the man page 
along with a warning to avoid including it as a permanent option - good 
enough reasons for not using it IMO.

Again, not useful as a permanent option since I don't want to receive 
duplicated messages.

In both cases using them 'as required' requires: 
(a) monitoring the source mailbox for 'read' message build up
(b) when 'read' messages are seen, executing a sequence of 
       stop fetchmail
       alter configuration
       run it for one retrieval session 
       change config back
       restart using the normal configuration

That's far too much hassle to be part of SOP. 

Now, if ESR had fixed fetchmail to tidy up after itself (if getmail can 
do that, there's no reason why fetchmail can't) or had even added the 
ability for a daily or weekly cron job to enquire about 'read' messages 
and, if any are present, tell it to silently expunge them in a special 
session, I'd probably still use it. 

Without equivalent fixes its just a buggy bit of software, making getmail 
a superior replacement because it 'just works'.
