How to extend dependencies in an environment?

[GeeTransit]

Hello. I'm using Hatch for an application (rather than a library) and I have my dependencies listed in [envs.default].dependencies. I have another environment that contains dependencies for an experimental feature. Something like this (with irrelevant stuff removed):

[envs.default]
dependencies = ["dep1", "dep2"]

[envs.experimental]
dependencies = ["dep1", "dep2", "new"]

Is there a way to not repeat the stable dependencies?

I tried inheritance (with [envs.experimental].template = "default"]) but it overwrites the dependencies instead of extending them.

I also did some experimenting with matrices and overrides but that means I gotta do hatch run stable:app or hatch -e stable run app instead of simply hatch run app (though it's better than nothing).

I also tried using [project.optional-dependencies] but my app isn't pip-installable just yet (I have [envs.default].skip-install = true).

Hey, thanks for opening this!

I could add an extra-dependencies option to environments. What do you think?

Yep that sounds good :D

Done!

Just tested it and it works fantastically. Thanks!
