What does technically capable mean though? There are a lot things you can do in the controlled environment of tests conducted under ideal conditions with the planes flown by highly trained test pilots. Then you have the real world where LTjg Bob "Snot" Rag is trying to bring the beast down on a pitching deck in lousy weather.
IIRC the HMS Invincible sailed south in 1982 with a smashed coupling, so could only use 1 shaft until it was fixed at Ascension. If 'Vince was a CATOBAR ship and certain planes needed 20kts+ to generate enough Wind Over Deck then these planes wouldn't be able to operate for 2 weeks until the coupling was replaced. If operations meant that the Vince couldn't anchor and have have the coupling flown out to be fixed then she'd have to operate at half power until able to withdraw from operations, and these planes would be able to operate at all.
This is the sort of reason why planes which can theoretically operate from a certain ship don't actually do so. If a ship needs EVERYTHING to go right to operate a plane, then it can't operate that plane.
