A combination of the two.

It does what the display code does.

As for what's `more logical', I find that both methods make sense,
depending on what the intent of inheriting from multiple faces is (and
of course, the code can't tell your intent, unless some method for
specifying it is added).

For instance, if I have faces:

  `double' -- :height 2.0
  `triple' -- :height 3.0
  `my-face' -- :inherit '(double triple)

It seems rather sensible that `my-face' should have a :height of 6.0.

On the other hand, I may wish to inherit from two scaled faces to pick
up their other attributes, but really wish the size to simply be the
same as (say the first) one of the inherited faces.

In any case, any argument should be made about the way the display
works, not about `face-attribute', which should just mirror what the
display code does.
