With P1 now having doorless entry mode, it's possible in rare cases for more than 4 portals to be visible onscreen - if the entrance and exit worldportals, corridor 4 obs room worldportal, and both player portals are all visible at once. This is only made worse by the world portal item UCP (and #574 if we ever make up our mind on that). We've had fastpath disabled by default for a little while in P2CE and it hasn't caused any problems, so it'd probably be good to do that in BEE P1 maps. Perhaps Old Aperture as well since it has the large obs room worldportal, and I might add a doorless entry to 70s later on.
