I'm not sure how it got there, but it's not right anymore. I've
removed it.
The question remains of whether it is worth maintaining something
between v4t, softfp and v7, thumb2, vfp3, to better support things
like v6, VFP2. Someone would need to show that there was demand, and
sufficient speed improvements over existing armel.
I'm generally of the opinion that work to make it easier to rebuild Debian
for an optimised variant, and to have partial archives for optimised
packages is more generally useful than more full ports.

Yes. The page probably needs a bit more general revision to be
explicit about what options have actually been chosen, as opposed to
which were available for consideration at the time it was written.
