If your git monorepo is sluggish, a nice fyi https://github.blog/2021-11-10-make-your-monorepo-feel-small-with-gits-sparse-index/

Interesting read :)

It's welcome that they're thinking about how to optimize git for monorepo uses in particular.

As I read those articles, it occurs to me that pants integrating with that feature could be even better. It would be awesome to be able to ask pants to make sure my spare checkout includes all the dependencies I need for a target, or to trim my sparse checkout down to just what is needed for a target (or set of targets)

Interesting idea! Please do open a feature request so it can be explored more.
