To the best of my knowledge, this is not true. Have a link?

Agreed, but that's actually an (UX) problem that Debian should fix. "Testing" is an awful name for "stable enough for normal use". When I first installed Debian I made the same error of installing stable on desktop and then fighting with it to install packages from testing... Just renaming testing to "regular" would prevent lots of wasted time all around.
