Choose?
A lot of high performance aircraft are used for business travel. Much less than 20 years ago, but don’t get me started. When they updated the owners did not have a $1500 option. Your argument is based on a misrepresentation of history. My options, until nearly the deadline, were to upgrade minimally for maybe $6k? That option would have upped my value almost zero. OTOH, I could spend much more, but gain most of that in value.
I wasn’t flying for business anymore, but if I were, I’d have had to get my plane in the shop to avoid a predicted rush near the deadline.
Now for the rest of your solution, where is it? What does it cost me and how much performance do I lose? Where’s YOUR data?
I suspect no one will know the answer to how easy it is to modify a plane until a fuel is decided on. And, no bureaucrat wants to be the guy who decided on a fuel and then there was a bad outcome.
