I will still recommend the path that is the only one I have really seen

Make the new solution work so well that nobody wants to keep the old
one. (Yes, I know that will take a long time.)

If you remove txt-records, do you believe that will make all the people
with 8.x.x BIND servers upgrade just now? (or even 4.7)? I did not think
so, I also believe that more immidiate reasons will be needed for that
to happen. All the bugs and vulnerabilities have not succeeded yet.

That means that removing them will leave us without SPF in general; mail
will survive, but with more spam accepted for human handling. Whos
interest would that be?

In general I agree that a special RR-type is far preferable to txt-RRs.
