So, maybe sensing sudden loss of sphincter control could automatically trigger an abort?

We'll have to wait and see if that "four windows" comment was an oversight, or if it is indeed the new situation.

Does a porthole on the hatch count as a legit window?

And the crew should be in airline uniforms, with hats, and the stewardess should have a huge soft white egg on her head. And she should hand out a souvenir pen to the bored, sleepy passenger, subtly slipping it into his top pocket. Hey, don't disagree - this is the commercial flight to a space station we've been waiting for!Just ignore any warnings about defective AE35 units and nothing could possibly go wornggggg...I'm pretty sure btw that SpaceX will try to have easter eggs on the control panel. Something like a button combination brings out a huge SCE to AUX button on the screen.

More complexity means more chances of bugs.
Thanks for the replies but no one has really answered the OP, and I think the question is a pretty good one that I hadn't considered before. Could/would the crew dragon initiate an abort before the tank dome ruptures? If not, would a crew dragon with a damaged/destroyed trunk be able to abort safely?

The Draco and SuperDraco engines that would be used to move the vehicle away from the damaged launch vehicle are part of the Dragon, not the trunk, so the engines would not be affected by a damaged trunk. For Dragon Cargo it would jettison the trunk right away, but with the Dragon Crew the trunk is needed for directional control. See this NSF thread on the Dragon Pad Abort Test.
Exactly, the trunk is needed for abort stability, so in a situation where the trunk is damaged/destroyed before the abort initiates... will the crew still be safe? A corkscrewing/tumbling dragon under full abort acceleration seems like a pretty dicey situation.
After half a second of vertical flight, Crew Dragon pitched toward the ocean and continued its controlled burn. The SuperDraco engines throttled to control the trajectory based on real-time measurements from the vehicle’s sensors.
Reed: finished CDR for crew dragon spacecraft last week; in final review at NASA now. Went “very well.”
SpaceX’s Reed: Wrapped up Crew Dragon CDR last week, currently under review by NASA. Delta CDR in December.
