having inspected hundreds of plugins in the last years, I'm still unsure
this is a good approach. I think it induces bad habits (e.g. one plugin
had a modified gdal command, so these improvements were essentially
lost). For the very same reasons, this practice is formally forbidden
e.g. in Debian. I'm aware this puts some extra strain on developers and
users, but results in better software in the long term.

this seems quite right to me.

Cheers, and thanks for comments.
