Yes - it clones absolutely everything. If you’ve got untrusted devs, then it might not be the best thing. Personally, I’d get trusted devs!
As is, you would need to commit to cloning the structure in there that you need (e.g. settings, categories, groups, plugins, etc) and either maintaining it in sync manually, re-cloning it when needed, or developing your own solution to automate it.
Good luck!
