As I understand it it does not.
My understanding is that "source routing" as it is used in the contexts
in which it is (as you say) frowned upon does not refer to routing
based on ip_src, which is what's under discussion here, but rather to
obeying SSRR and LSRR IP options. The latter is completely orthogonal
to the type of routing I was talking about. (And, unless I
misunderstood, what the original poster was talking about.)
