Are you sure about that last part?

I have been running with (e.g.)

deb http://ftp.us.debian.org/debian/ stable main non-free contrib
deb http://ftp.us.debian.org/debian/ testing main non-free contrib

for over a decade, and while there have been some problems, I think
they've been basically the same ones I'd have seen from running testing
alone; none of them have seemed terribly difficult to resolve, either.
(At least not by my standards, although I'll admit that I may not be the
best or most representative example.)

I don't particularly consider this mixing releases; it's more tracking
testing, while still keeping available any packages which were in stable
but have been removed from testing.

IMO, if you're going to track testing at all on a production computer
(as opposed to, well, for the purpose of actually *testing the upcoming
release*), it only makes sense to also include stable; there's too much
chance of an important package being (temporarily or permanently)
unavailable, otherwise.
