Currently tcpconn.py uses netstat to get it's socket stats. This gives

tcpconn.py was originally written as an advanced python module example
as it shows how to do multithreaded modules and how to poll metric
information from an external source.
it was found useful enough and some people enabled it, if it made
sense for their environments (definitely not in HPC, or high traffic)
but since it is a module it can be replaced for something that fits
better on your environment like the proposal you had.
/proc/net/sockstat gives less
information but has no performance problems. There was a suggestion
previously to use the ss command, but (1) it's less common (at least not
part of the default on RHEL5) and (2) it also lacks the high fidelity
details.
Is there any other reason to prefer ss over cat? Should this replace
tcpconn, or be a new module?
most likely (for the reasons explained above) would be a new module
and if you are concerned about performance, mos likely in C
