The general trend for such code to not have an explicit maintainer. 
Instead changes get approved using peer-review that involves at least 
one core maintainer.  Anything architectural being pulled out and 
discssed separatly.

I should also red flag that changing the target vector means changing 
the thread code so "it could be fun times".
