Comment:
In addition to any warnings as to the keyword being deprecated, palliative and temporary, it would be really helpful to have a description of how it actually works as is. I understand that this might feel like a step towards "legitimizing" it and leaving it be for a long time, but it's been there for a long time already, used in many packages, and therefore I think it's better to have it properly documented.

To motivate more people to consider using transitional packages and other alternatives to this keyword, I suggest introducing some highly visible warnings to the packaging tools like `xlint` or `xbps-src` shown upon encountering `replaces=` in a template.
