Why there is no '--enable-optimizations'  for python 2.7 images?

Hello Folks,

Looks like the python 2.7 images aren't using the '--enable-optimizations' in the configure step of python compilation (https://github.com/docker-library/python/blob/cf68ae064414062b255c7074c58f46e81b31c92e/2.7/buster/slim/Dockerfile#L62). Is there any problem or reason to do so?

I just built an image locally with the flag and it worked.

Thanks in advance.
