[imp] hide messages marked for deletion or purge deleted messages

I realized I am biased, but our way of doing this seems to make a  
whole lot more sense than Thunderbird's way.  Move message to Trash  
when deleted means just that - when I click move I want that message  
to be gone forever from the mailbox I am deleting from.  This needs to  
be an atomic operation, not a lazy operation.

Because you would be making an *extremely* ill-advised assumption.  If  
you set "move messages to Trash" option in IMP, that literally means  
"move any message I delete using the IMP interface to the Trash".  You  
apparently want that to mean instead "move any message I delete using  
the IMP interface, along with messages that I may/many not know are  
deleted, and may not even appear in my current view, to the Trash."   
But that's not what IMP's option says it is going to do.

Deleting *any* message is the most destructive operation possible with  
IMAP, so you need to make especially sure that you are 100% sure the  
user wants to delete.  If you are only 99% sure the user wants to  
delete those messages, you simply can't do it.  Those are just the  
facts of life (and UI design).
