Should local only communities be viewable without login?

[Nutomic]

Question

Communities with visibility "local only" can be useful for meta discussions about the local instance, where users from other instances shouldnt be able to participate. However it may be relevant for new users to browse such a meta community before registering, to get an idea how the instance is administrated. In case of lemmy.ml we had /c/meta as local only, but had to change it back to public because the post What is lemmy.ml? linked in the sidebar was not visible without login anymore.

It would be very simple to make a change so that local only communities can be browsed by any user without login. They would still not be federated to other instances. Another option would be a separate visibility level which disables community federation, but allows viewing it without login.
