No, but in some cases it's enough to at least start asking the "who uses 
this code? should we continue maintaining it?" type questions.

In the cover letter I did say this:

"The idea behind putting out this series is to either establish that 
these drivers are used and should be maintained, or remove them."

We have established that these drivers are indeed used, and thus 
shouldn't be removed.

There's no tag that I am aware of. I have seen people say "NACK" or 
"please don't do this" followed by an explanation of why the 
patch/series is a bad idea. For example, see the other responses to this 
series.
