@icon_of_computational_sin Fair enough. This is the sort of thing that made me interested in it in the first place, because that does sound nice; though in practice I do this anyway, because any package I have installed for development only tends to just not interfere with anything else. I am the sort of person that will look at you in confusion if you suggest developing against an old version of anything. Obviously I will update my software to adapt to changes in its dependencies. In general, I assume that updates are released for a good reason, and if I discover otherwise, I throw it straight into the bin.
