I don't get what PEP 405 (Python Virtual Environments) brings vs what we
already had in PEP 370 since Python 2.6.
Obviously 405 has a tool to create virtual environments, but that's
trivial for PEP 370 [1], and has support for isolation from the
system-wide site patch which could've been added in addition to PEP 370.
So maybe I'm missing something?

well you can have and activate several different directories (venvs) with PYTHONUSERBASE. I do use that very nicely, and haven't seen any problems with that.

Wouldn't it be easier to just add isolation to 370?
Again, you can have multiple virtual envs with 370 too.
ps.
sorry for the late response, it seems my NNTP server doesn't relay all messages. I might need to switch.
