Thanks for bringing the thread to the kde list.
Concretely, I see 2 low-hanging fruit to seriously consider:
* drop kde telepathy stuff from the spin. It's largely deprecated and
unmaintained (almost got dropped from kde-apps at prior maintainer's
request). No replacement (we have kopete, but it's still kde4-based, so
meh).
* drop one of the extra non-default browsers (*): qupzilla (soon to be
renamed), konqueror. of that list, konqueror is likely the least useful to
most users.

p.s. (*) and if folks want to re-open the can-of-worms default browser
topic again, please do so in a separate thread. My take per the last time
it was discussed is that we can't act on that until qupzilla is renamed.
