example.com/latemigrate/v2 v2.0.0
written by hand

This repository migrated to modules in v2.0.1 after v2.0.0 was already tagged.
All versions require rsc.io/quote so we can test downgrades.

v2.0.0 is technically part of example.com/latemigrate as v2.0.0+incompatible.
Proxies may serve it as part of the version list for example.com/latemigrate/v2.
'go get' must be able to ignore these versions.
