Conditionals could perhaps be handled in different ways, e.g.

1. Markers as used in distutils2/packaging (where the condition is platform or
version related)
2. A scheme to resolve variables, such as is used in PEP 391 (dictionary-based
configuration for logging).

If conditionals are much more involved than this, there's a possibility of
introducing too much program logic - the setup.py situation

and code reuse between hooks. I don't see any drawback to using only one file ?

I was assuming that the dist.yaml file would just have callable references here;
I suppose having (sizable) Python fragments in dist.yaml might become unwieldy.
