I don’t follow.  I don’t see what you’re referring to as “brittle” and
what you need to keep in your head.

You can manage your profile with a manifest; in fact, we recommend

always the best fit.

And yes, you can use inferiors in your manifest to build a profile made
of packages from different versions of different channels explicitly.
