They serve different needs. Quite a few options do not make sense as
profiles. What do you do with parallel=n? None of nocheck, noopt or
nostrip should change any package relations. noddebs changes which
packages are built, but those are not part of d/control anyway. Then
there is the non-standard but frequently used debug option.

As Ian pointed out, it may still make sense to transition some options
to profiles.

I actually think that it should be possible to use the result of a
bootstrap as is. You see, that's exactly what Yocto, Buildroot, PTXdist,
and others do. Just Debian has much better security support, long term
support, package quality and quantity than any of the contenders.

Yes. Obvious omission. It is not clear though whether bootstrapping with
or without audit is easier.

It's crucial for an algorithm to be able to choose profiles. I want to
remove the need to have to think about which stages are necessary.

It matters as soon as your reverse dependencies fail to build. Spoiler:
They do occasionally.
