So how can this be a flaw?  It is obviously by design and here is why:

All clears up if you consider how it all used to work before 3.1 when there
was no interior.  Back then you could (you still can more or less) create a
layered texture with *different* refraction on each layer - an obviously
nonsensical (and obviously impossible) flexibility caused by the addition of
layered textures.  So layered textures are closer to layered pigments,
defining everything for the color part of a texture - you are forgetting that
both _textures_ also have a default finish but not all options make sense when
combined.

Sure, this isn't the optimal solution, but it is not a random design decision
or flaw either.  And sure it will not be fixed in 3.5 because it is not a bug.
Of course, for POV-Ray 4.0 a better solution that adds more of the flexibility
you are looking for should and will be considered...
