I partially agree. In the sense that I would port regression fixes constantly (THIS is important security-wise), I would NOT like to have updates to major releases, as this means breaking-changes and it's against the whole Stable philosophy. GCC 6.4 is going to be released soon and I hope Debian Stable will get all those regression fixes that update will inevitably bring to the table. After my experience with Jessie (which still offers GCC 4.9.2 although version 4.9.4 fixed an impressive list of bugs and it's not even available in the backports), I'm not going to be so optimistic. This is so important it should not be left to the volunteers' will.
