The problem is that the above *makes no sense*.  "Torqued Python" and
"Gorgon" are veiled pseudonyms for Twisted and Medusa....  and Twisted is
not actually a plug-and-play substitute for Medusa, AFAIK.

Can anybody suggest an *actual* use case for "Obsoletes", and explain how
it is supposed to work in software?  The last time this discussion came up,
nobody had any use cases that stood up to the "how's that actually going to
work and/or help?" test.  Here's a post of mine summarizing this and
related points in the previous thread:
