> Hm, indeed, but I see that module 'abc' is in 'sys.modules', probably it is then only used by ''/'_collections_abc'. This means that the influence of 'ABCMeta' on interpreter start-up time will be smaller than I thought. But still start-up times for projects that actively use ABCs will be influenced by 'ABCMeta'.

Since os.environ uses _collections_abc.MutableMapping, importing _collections_abc is not avoidable while startup.

`io` module uses ABC and it's used for sys.std(io|err|in).  It's not avoidable too.

And as you know, typing module will be very common rapidly :)
Even if it doesn't affect "python_startup" microbench, it's important.
