It's two separate subsystems. There's a lot of non-tracing aspects of 
performance events: it does profiling, counting, latency analysis, etc. 
The tool is named 'perf', the subsystem is named 'performance events', 
and the most typical workflows dont do any tracing.

And i beg to differ about the size of the communities. It's just been 
added upstream...

Also, what is the policy for adding new lists to vger.kernel.org? If a 
subsystem maintainer asks for a list named after a core kernel 
subsystem, how frequently is it rejected, and on what basis?

I find it sad that such an arbitrary looking negative decision from you 
forces a user list away from vger. I wouldnt mind it to be closed if it 
has no significant traffic after a year or lifetime or so - many vger 
lists have almost no traffic to begin with.

Also, i cannot help but to observe the fact that you've fought the 
original perfcounters project in a very ugly and public way less than a 
year ago. Dont you think that you 'deciding' this matter in such a 
negative fashion is a conflict of interest?
