Hi, Mergin Maps plugin also packages the dependencies (including the geodiff binary) into the plugin itself. I’m not sure how it handles cross-platform differences, though.

This also tackles the problem with different versions of the same requirements between multiple plugins. There is a tool for that https://github.com/nlsfi/qgis-plugin-dev-tools which also has many more useful features for developing QGIS plugins. One example of plugins using this tool is pickLayer (https://plugins.qgis.org/plugins/pickLayer/) which bundles https://github.com/GispoCoding/qgis_plugin_tools with it. What do you think about this approach?

Agreed this is not ok. I think a plugin downloading anything to be executed or interpreted should be entirely prohibited. +1 . This practice should lead to a plugin being removed from the repositories. (Possibly we could do something on the code side too, eg by monkey patching over subprocess/etc and explicitly blocking execution of sip, with a developer-friendly exception stating this policy. It'd be easy for someone motivated to circumvent, but could at least be used to advise plugin developers that this is not acceptable practice...) We've tried to come up with a more transparent approach with support for requirements.txt (see https://github.com/opengisch/qpip). It is using pip but with a frontend which informs the user and lets him confirm an eventual installation. Is this approach generally acceptable? Well, I definitely trust yourself/OpenGIS significantly more then other random plugin developers 👍 I would personally feel safest if this was something officially endorsed, with an explicit allow list of acceptable packages.
