Hum, this one might be nice to just integrate into the official module? Not
sure if there are any unforeseen side effects, would be good to see the
sources.

This one might get obsolete soon. What you are doing there is processing,
which is in the realm of WPS.
The WPS extension could trivially do what you want above if someone writes
a centroid process (should be quick).
Right now using the WPS extension is not so safe in that it comes with a
mix of quick and heavy processes,
but we should get the ability to cherry pick what processes to expose
rather soon.
I guess the only downside left at that point would be that WPS is a
different protocol.
Anyways, don't take any of these as a rejection, just as a discussion.
If you want to contribute those as community modules you have my +1 of
course, just exploring alternative
approaches to integrate your work.
Cheers
