For a definition of cautious I don't personally share.
Debian doesn't vet packages. Debian maintainers are less competent than the "upstream" they question approximately all the time, which is why they keep breaking stuff in more or less severe way (OpenSLL anyone?). And let's not even talk about the insane stuff like when maitainers decide to support a fork they like instead of the piece of software users actually want (Libav anyone?).

And that's your choice. That doesn't mean developers should care, nor that it is actually a good idea.
