Team updates in effect will prompt revisions in the manual at some future date. Q&A are usually answers to directed questions that are answered in relation to the current rules as reflected in the manual/team updates. If team makes a design decision based on a Q&A, I expect them to have the documentation to show. Not every volunteer/ref/FTA/inspector will have access to or a hard copy of the Q&A.

In respect to the bumper in the last team update, please note that the bumper zone is referenced to the robot sitting on a flat surface when determining the bumper zone. Additionally, the bumper zone is not checked when a robot is traversing the barrier or the bridges per the latest team update.
So, to be clear, the view of the Collected Wisdom is what?

Specifically, do we have to pretend that someone may freeze time and place our robot on a flat floor and if our bumper is outside the bumper zone wrt that flat floor, we are in violation of the rules at that moment in time?

OR...

Are we exempt from that rule when in transitions to/from the barrier?
Are we exempt from that rule when in transitions to/from a bridge?

AND...

For the record, I think that FIRST should go to the "bumpers must stay inside this zone" rule define the zone in real world (not robot) coords (perhaps with a relative to a moving field element if robots have to drive over it, e.g. a bridge) and the penalize teams for actual violations not potential violations.
