 In the discussion around #22820, we decided that giving the exit flag to
 relays that exit to ports 80 and 443 is the right thing to do:

 First, port 6667 used to be relevant, but now, and especially with the
 advent of ircs, it isn't.

 Second, we invented the current algorithm for the Exit flag back before
 Mike invented the 'reduced exit policy'.

 Third, a relay that exits to 443 but not 80, or 80 but not 443, is going
 to make web browsing super bumpy when used with Tor Browser's tab
 isolation strategy.

 So we should simplify it.
