The Description-Content-Type field has been added to the spec:
https://packaging.python.org/specifications/core-metadata/#description-content-type-optional

(This was part of the motivation for Dustin's metadata 1.3 PEP, to
help make it more readily apparent that we'd added that)

So the missing step is the "plumbing through" part, such that the
publishing tools support setting it, and Warehouse supports ensuring
the description renders at upload time.

However, there's still a difference between "renders without error"
and "renders the way the developer intended", so your initial post
will still stand for those kinds of problems (as well as typo fixes,
etc).

Cheers,
Nick.
