Pex now supports setting defaults for environment variables and injecting default arguments for the entry point chosen at PEX build time. This eliminates the need for projects like https://github.com/kwlzn/pyuwsgi_pex and makes it easy to package a PEXed framework app where the main entry point is fixed in the framework and the hooks are configured to point to user supplied entry points. This removes the last known legitimate API use of Pex and paves the way for Pex 3 to be cut in good conscience with a CLI-only API that does not hinder any known use cases. Fixes pex-tool#987
There is. There are only 2 Pex runtime entry points, |

The
__pex__import hook introduced in #1845 removed the need forprojects like https://github.com/pantsbuild/lambdex. This change removes
the last known legitimate API use of Pex and paves the way for Pex 3 to
be cut in good conscience with a CLI-only API that does not hinder any
known use cases.
Fixes #987
