Here is my take on the subject.
There are 1517 instances of @rev
"made" occurs 83% of the time (1259 instances)
"stylesheet" occurs 8.2% of the time (124 instances)
The rest occur 8.9% of the time (135 instances)
the misuse of "stylesheet" is trivial and only a matter of informing
authors of their error, the fact that a high amount of authors are using
rev-made is Inspiring to say the least, because every made link type is
a claim of ownership, not authorship two totally different semantics.
I will study the results of @rel soon but from first glance It seems
there is (statistically) more abuse and misunderstanding about @rel than
there will ever be than @rev
