What you folks in EASA-land need, is for the
FAA to take over.
Much better, and far less expensive...
Having personally held an FAA ATPL for over forty years, with numerous jet, turbopropellor, and large piston type ratings, never once was I charged for a rating endorsement.
And, least you think that a large aircraft type rating is an easy exercise, try it sometime with a hard-nosed FAA inspector...
