I believe that the term 'cow path' refers to something that has a lot
of usage. I.e. something that people use or do a lot.

So I definitely agree that the fact that UAs don't use the profile
attribute does not make it a non-cow-path.

The question is instead, do pages use the profile attribute.

Based on this very small data sample it does not seem like @profile is
heavily used for hCard pages. Thus, if this data is representative,
there would be no cow path.

We can also guess, based on the fact that it seems to make
little-to-no difference if the profile attribute is present, that many
people don't put the profile in, either out of forgetting, not
knowing, or simply not caring. However this is just a guess and actual
data is of course much better.
