There is a finite number of people that need to advertise a /16 on the
IPv6 DFZ at the same time for the sole purpose of experimenting a new
protocol.

Wrong.

Absolutely, and there needs to be no authority for that.

Why?

This is not even debatable. Not everyone needs global experiments, but
some people do. In the case that prompted all that turmoil
(shipworm/microsoft), there is no doubt that whoever develops such a
protocol will one day or another need to advertise a /16.

Hijacking is bad, but regulated hijacking could have some use,
especially if it does not break anything.
