[gentoo-dev] Eclass support for installing shell completions for Click-based Python applications

[Anna (cybertailor) Vyalkova]

dev-python/click has out-of-the-box support for generating shell 
completions:
https://click.palletsprojects.com/en/stable/shell-completion/

Since it's a popular library, multiple packages can benefit from a 
streamlined way to generate and install shell completions.

Three most obvious places for this functionality would be:

- A new eclass

    I'm leaning towards this option: just write it and leave in ::guru 
    for everyone to use. I didn't want to start this discussion in the 
    first place but was asked by a fellow member.

    And anyway I don't know how to name such eclass, would like to see 
    your suggestions...

- shell-completions.eclass

    Its name fits the purpose, but it would be a mess to start extending 
    such a simple eclass.

- distutils-r1.eclass

    Something like distutils_enable_sphinx but for shell completions.


I also don't want to discuss implementation details before any code is 
written, it would be just empty talk right now.

So, am I right that this functionality should be implemented outside of 
any existing eclasses. And if so, how should it be named?
