This should definitely be doable, but I'll have to ask the team about
their opinion. (Cons: Minor feature, increases reserved keyword clutter...)

It indeed seems a bit strange that given that reflection is a property of
the texture and not the interior, it would use a value from the interior.
(I don't know the details of the theory behind fresnel reflection, but
I could easily imagine a surface having a different ior on a thin reflecting
layer on its surface than in its main body, thus causing a different type of
reflection than an uniform object would have...)
Someone who knows the theory behind fresnel reclection could express his
opinion on this.
