Slow performance, especially in a widely used library like cl-lib, 
is a bug.
Where would you prefer such observations be reported?

As stated, I've done that and am aware of the general 
performance/flexibility trade-offs.
It would be preferable to improve the performance of that 
function, as it would benefit anyone using it.

Are you confident the performance trade-off is due to dispatching 
on sequence types in this case?
Do you think the performance could be improved without sacrificing 
that flexibility?
I'll dig into it more when I have time, but I'm starting a 
discussion here in case someone has already made an attempt or 
knows the answers to those questions.
