validateCapability in ForgeCapabilityKey uses a fair amount of resources on the main thread for string formatting, regardless of whether the capability is null or not. Changing the string to a constant or using the Supplier<String> overload should fix the issue. I see that the same paradigm is used in a few other places throughout the repo, but I haven't seen issues with any of those.

This seems to significantly hurt the performance of Thin Air, specifically.
