"The fstop items are ones that ‘release’ the braking pressure – not disarm the RTO. "
Fair enough...I stand corrected. After takeoff, the ABS will no longer be latched in the RTO position due to the above.
One of the reasons (there are other reasons) some train to
not set the parking brake when lining up to wait is because of this high profile accident:

The National Transportation Safety Board determines that the probable cause Of the accident was the flightcrew's failure to release the parking brake before the takeoff roll was started, which resulted in significant wheellbrake drag and a nosedown pitching moment that inhibited the aircraft's capability to effect a normal acceleration and rotation for takeoff.
