Never good to see them full. It means slower charging.
You should want to see them half full.

Actually, V3 Superchargers do share power across stalls. Each cabinet has a limit and there is some kind of sharing between cabinets as well. They are not nearly as constrained as V2s are, but there are limits that get hit when a V3 site fills to the max. I've seen it discussed in YT videos, but here also is a discussion thread at TMC: V3 Supercharger power systems architecture
DC bus sharing can be implemented between v3 cabinets, but I'm not sure it's always implemented. I think an 8 stall (pre-fab/PSU, and possibly also traditionally built) v3 sites may not always have DC bus sharing. This likely stems from the cost in materials and labor to install it vs. the likelihood of a site actually needing the shared bus for peak charging demands. I think 12+ stall sites probably all have the shared DC bus. It's possible this info just applies to pre-fab units - not sure.
Tesla doesn't have <number of stalls> x 250kW available precisely because the peak power would always be used. When sites fill up, people usually see some charging limits.
So, people definitely report slowdowns at busy sites.
From what I’ve seen, every V3 has load sharing between cabinets. And with that being said, the likeliness of all of the cars requesting full power is pretty low.
The comment on it me being happy it was full was that I was curious if this charger would be busy or not.
