    Could you give a simple example of how a current use of `modify-face' would
    be replaced with a call to `face-spec-set' or `defface' in your proposal?

You need to write a function like `modify-face' that constructs a face
spec out of the args, and then calls `face-spec-set'.

If you want it to change only certain attributes and leave the others
unchanged, you would need to call frame-attribute to get the values of
the other attributes, and perhaps put them into the spec you
construct, so as to make sure they won't be altered.
