A rose by any other name…
I don’t think renaming the metric would ever allow people to ignore the constant fretting and comparisons that occur with FTP. That would likely be true even if they took the step of making something entirely “new” that wasn’t FTP in disguise.
That metric would still vary from person to person and over time for the same person. The desire to evaluate, grow and compare something like that is innate in humans overall, but even more so for people in this area.
We see growth and competition on an internal level at the very least. And that expands to external in most cases as well. My point being that you can’t escape the inevitable outcome of people comparing anything that can be measured. Add in our fragile EGO and all bets are off, IMHO.
