Not really; please see paragraph (c) in my other reply at <https://lists.01.org/pipermail/edk2-devel/2019-January/034762.html>. The rationale is given in the blog post at <https://developers.redhat.com/blog/2018/11/14/python-in-rhel-8/>, near the "platform-python" mentions. Basically the OS should be able to offer different Python3 installations (at the same time) to end-users and internally to OS-level packages. Thanks!
