[Feature Request]: Tag / Label for experimental modules

[luc122c]

It would be great to be able to list experimental/pre-release modules with a clear indicator that they are not production ready. I imagine this would appear like the "sponsored" and "official" tags. I'm specifically thinking about the first-party Sentry module but I'm sure there are more modules under development. I see the following benefits:

• de-duplication; someone is less likely to begin work on a module if they can see one is already under development
• testing; increased visibility of pre-release modules will hopefully increase the number of beta testers and improve the module

I'd be happy to work on this, but would appreciate some guidance. For example, what would the preferred wording be? Would this be a boolean attribute like Sponsor?
