No, as I said so many times already and you're unwilling to understand
it: multiple policies support in cpufreq should be optional and
selectable in Kconfig so that systems which don't need that, don't
have to see or use it. It is yet another feature which doesn't apply
universally so we make such features optional. Like the rest of the
gazillion things in the kernel already.

The existing sysfs layout cannot be changed because you're breaking
userspace and we don't do that. It is that simple.

Concerning adding new sysfs entries, I told you to make it as easy as
possible and as sensible as possible, dictated by the use cases. If you
can't come up with some, then talk to the people who are going to use
your design and ask them what makes sense the most.

*Then* write the code.
