I'm no IMAP expert, but what you state here doesn't make any sense at all.
With the exception of early FTP implementations, I've not seen any/many widely
used protocols that require different/multiple sockets for different types of
data or commands.  This is the total opposite of efficiency.

I just sent myself a test message from gmail and within a second of watching
postfix smtpd fire the email showed in my inbox in TB.  This shows that IDLE
is working with only a single IMAP connection to Dovecot.  I don't really have
a way to test your "IDLE per folder per connection" theory as all my folders
are list mail folders populated by a sieve script.  When I send this I'll
watch top and see if it hits immediately or has to wait the "check every 1
minute" setting in TB.

RFCs are a huge PITA to read and digest.  I may take a look if required, but
for now I think this theory is malarky.  No offense intended.  Just calling it
as I see it.
