I mean, heck, MLB - which has recently gotten much better about this after having been so bad in the past that they deleted their old ETA projections - still has an ETA on Hassell of 2023. Dude has a total of 108 PAs in AA, during which he looked overmatched. They project Noelvi Marte - one of the guys in the Luis Castillo trade, who is 20, has never played above high-A, and is blocked by two top-100 prospects at his position plus a former top prospect presently flopping but not out of runway on that org's MLB team - as arriving in 2023. What about either of those situations suggests a guy who will play in the majors next year?
Well Marte has 200+ minor league games under his belt and has actually hit well above rookie ball.
