Old wheels may have broken descriptions

[di]

In #3058 we figured out that a wheel built with wheel==0.24.0 had a broken description when uploaded to Warehouse. Upgrading to wheel==0.30.0 fixed it.

If we have a way to determine what version of wheel the wheel was built with, we may want to warn the user in some way (from Warehouse? in twine?) that it could result in an incorrectly rendered description.

Look a *.dist-info/WHEEL, that should contain what was used to build it, but not sure if it includes version information or not.

Seems like maybe this issue belongs over at pypa/twine instead since we're not doing much introspection of the distributions.

About how many projects do we currently have where the most recent release has a broken description because of this issue? I presume that's something I could figure out via Google BigQuery if I figured out how to use it.

[di]

I don't think it's possible via BigQuery, as Donald said, the version of wheel used to build the distribution is in the metadata, but we don't extract it or do any introspection of the file.

I haven't seen many reports about this, and there might not really be a good way to fix it, so this shouldn't be high-priority (folks should just update their wheel).

Closing this since we no longer allow uploads with invalid/broken descriptions, so the point is moot.
