You're hardly bending over or jumping to tunes unless you've really stuffed things up with them, but merely playing to their ego's as part of a suite of tactics to get what you want - if they are happy they'll give it to you.
CASA is ruled by fear just like the rest of aviation. CASA people have a fear of being blamed for adverse events within the section of industry that is under their purview, plus they are subject to internal politics as always, and want to cull out the 20% of operators found in the 80/20 rule (Pareto Principle) that will make their lives worse off. Keep out of the 20 and jam yourself well into the 80 and they'll go someplace else to spread their misery.
