Would this be considered a bug?
Meshes allow an interior texture, but if even one triangle has an individual
texture, the entire 'back' of the mesh reverts to the exterior texture.

Please don't put the whole thing in the subject line and then just ask
"is this a bug?" in the article itself.

I didn't. It seems my message got cut off, perhaps because of the long
subject line. I apologize.
I said that meshes allow an interior_texture to be applied to them, but if
even one triangle in the mesh has an individual texture, then the entire
back side of the mesh reverts to the exterior texture. Would this be
considered a bug or is it a limitation of meshes, i.e. too complicated to
get exterior, interior, and individual textures simultaneously?

Use a reasonable subject line next time. There is no reason to make the
subject line any longer than it needs to be to identify the subject of
the message. Just don't go the other direction and use subjects of
"Help!" and "Bug!".

Not too complicated, but it would probably require more memory. It might
be that nobody noticed a mesh would require special coding for it, or it
might be that it wasn't considered worth the overhead.
