Container registry auomated garbage cillection sign in

In the DO Container Registry, I’ve been seeing the following pop-up:

#### Try automated garbage collection in Public Preview
Automatically reclaim storage space while your registry remains fully operational.

Unfortunately, there’s almost no information provided about what “Public Preview” actually means. There are no details on what enrolling involves, how to opt out later, or any clear documentation explaining the feature.

I’d really like to try this functionality, but I have a few concerns:

• Is it free (even temporarily)?
• Will it always remain free, or is there a future cost?
• What happens after opting in—can I easily disable it?

Some clarity around these points would be really helpful before deciding to enable the feature.
