I don’t use the docker labels feature so it doesn’t really matter to me but can see why you would want this to be implemented if you did. Hopefully they can figure it out.
I have a “local” version with every prod service on. It’s only accessible on my home network with a pihole dns resolver. I just add the services manually to the services.yaml file, which doesn’t take long at all. I then have a “remote” version which is a much smaller with only services accessible outside my home network and is behind nginx/authentication software/cloudflare. Again, it doesn’t take long to add services really. Two different docker compose files, volumes with the settings, and ports makes it work fine for me. I guess depends how often you’re adding services.
