The feed creator needs to know about the communities so they can type/paste the community address in, yeah. This feature takes the expert fediverse landscape knowledge contained in the heads of the terminally online and makes it available to more casual/new users.
Once a community is known to an instance it is available via the search feature. Thus this really doesn’t improve discoverability at all assuming the person adding it to the feed is already using the instance.
What it however does is moving the conscious choice of looking for and joining a community to an opaque follow feed button that makes someone subscribe to a lot of communities they know nothing about other than that someone else thought they somehow fit to a single word tag (and it is worse than hashtags on Mastodon as it is not the person making the post that adds them, but a totally unrelated 3rd party).
