Not really I think. I kind of subscribe to the same argument (I think it is the
same argument at least) for almost all software I install:
 - I want fast and low-risk updates in the case of a security update, so
   please give me a patch that fixes only the security issue
 - I want a low-hassle installation, so frequently updating (more frequently
   than every other year or so) is really annoying. Especially if there could
   be changes in the configuration that I have to adapt, and even more so if
   I cannot have confidence that all configuration changes I might need to
   make are given during the update.
 - I never want a software to update without my knowledge, so absolutely no
   phoning home for updates/automatically updating. Even without root. Being
   able to execute a binary on a system is not very far from being root on
   that system these days.

I think I apply this to every software with the exception of Tor, and for Tor
I only do it because of my project involvement and the big trust I put into
the maintainers of our repository. For other stuff, I just stop running it
if it doesn't work out of the box provided by my distribution.

Cheers
Sebastian
