I have been developing in Node for a few months now for non-Python projects (legacy project) and I found a NPM feature which could be helpful to developers of Python libraries.
When you install a NPM package, some show a message from the author after installation (see example below).
The project needs your help! Please consider supporting of core-js on Open Collective or Patreon:
Also, the author of core-js ( https://github.com/zloirock ) is looking for a good job -) ------
Is it possible to adopt this? My proposal is to add an entry in the package metadata which I believe is safer and easier to implement compared to running a post-installation script. It is up for developers of package managers (pip, poetry, etc.) to actually print these on the terminal.
I appreciate comments and feedback.
