Just some philosophical thoughts on advanced quals, community SOP, community dogma, and flight hour budgets-
Yes, it hurts everyone when there are restrictions on what the stick monkeys are allowed to practice. The community pays a price on collective proficiency by doing that to stretch old aircraft and keep them flying for a little longer, a little longer... so how do you balance that?
Speaking as someone with a decent amount of experience in instructing experienced pilots on advanced emergencies, I "get" the institutional approach of "airframe/community X"'s standardization program that restricts practicing certain maneuvers and emergency procedures to advanced qualifications. Here is why:
Good or bad pilots, with about a few years of flying and about several hundred hours, while training on how to instruct advanced emergencies, are capable of getting the aircraft into trouble in ways that... umm... that can get far more "sporting" faster than you realize how deep a hole you've just dug. They can also do so in ways that put the exciting mistakes of new guys (flight students, nuggets, etc.) to shame. The right time to abort some particular advanced maneuver might actually be while it doesn't seem all that messed up and there is only a subtle hint. 99% of instructing a someone on how to handle any given emergency is not all that much different from when you were the new guy and learning that EP, but- it's that other 1% of the time that can really sneak up on you. So it makes different sense to community X or Y on whether to restrict emergencies A, B, or C and who is allowed to demo, introduce, practice, or simply never attempt them.
I maintain that any newly minted aircraft commander could train to an acceptable standard to instruct just about any emergency that is in your aircraft's playbook. It's not a question of brains or hard work. It's not a question of "you don't know what you don't know" - someone else already knows what you don't know, it's written down somewhere, and you can learn it. It's a question of where the community wants to spend the money and the time.
(Last thought- it never hurts to have a look over the fence at how community Z does business...)
