If this is truly the case, I think the market will decide, and users will
move to those ISPs that make the move to native connectivity

I agree that this can seriously have the potential to again create the
same dual-class networks (Legacy vs post-RIR) we have in v4, where those
who got in early got a vast amount of address space and those who came
later were less fortunate.

I can live with this, although I expect these will live much longer.

In considering your arguments (and some of my responses), I'm now leaning
this way as well. I think it's actually a good thing that we attach some
sort of stigma to these prefixes to emphasize their temporary nature.

What do you propose these are?

Seems entirely reasonable.
