Yes.  The effect you see in Linoleum[1] is *exactly* reflection blurring.  If
you really had a perfectly smooth Linoleum with no blurring, you'd find 
that it didn't exhibit the effects you associate with Linoleum.

However, there's still a place for faded reflection in the POV toolbox.  It's
definitely the case that no matter how we do it, real blurred reflection takes
a lot of horsepower.  If faded reflection is good enough, there's no reason
it shouldn't be used.  However, I don't think it actually works.  To work,
it would need to fade based on the distance normal to the surface, not the
total distance.  That's just not practical.

[1] Linoleum is - or at least was - somebody's trademark.  It's only fair to
    capitalize it.
