I posted a proposal in Python ideas that I think deserves to be discussed among core devs and the community. In short, it aims at providing a way of customizing Python startup in a similar way of what sitecustomize provides today.
Link to the discourse thread: https://discuss.python.org/t/add-folder-for-python-customizations-sitecustom... Link to the proposal in a pepish format: https://gist.github.com/mariocj89/36daffd1e157b93e5c697bbadcb05806
I'd appreciate feedback in the discourse thread if possible. If this looks reasonable, Pablo Galindo would be my sponsor for submitting the proposal as a PEP.
Thanks a lot and happy holidays :)! Mario
