The requirement packaging>=21.3 makes Hatch impossible to install it alongside Poetry 1.1. (Here the blame is definitely not entirely on Hatch!)

Also, click>=8.0.3 is less than a year old, and occasionally some package may pin click <8.

Since Hatch is a build tool which may be used in large environments alongside older dependencies, it would in general be nice if its dependencies were left a bit looser, perhaps vendoring newly introduced functionality. Or does Hatch make essential use of these new versions?
