These are some rule lawyery but otherwise good points.It actually leads to another interesting thing.... can a creature move without speed?
Manuevers suggest that....yes, you can. For example, the charge manuever allows me to gain extra movement beyond my speed (and has no technical interaction with speed itself, I just move a straight 30 feet regardless of what my speed is normally).
Therefore.....by the book, I could use the charge maneuver to escape a grapple.
Further, a friend of mine could use press the attack against me, granting me 5 foot of movement (even if my speed is 0 or has been fully used in the round) and escape a grapple that way.
Now I think these are very RAW interpretations, not RAI at all.....but technically, it should work.
There should be a proviso in all these mechanics saying that if you're restrained, grappled, paralized, stunned, or your speed is otherwise zero for any reason, you cannot take those actions.
Which would also mean that you cannot use fall back when grappled, so grappling someone would be a good way to give an ally the expertise die on attacks
