Shouldn't we simply reject anything that ends with a trailing . as that's never going to be a valid config key anyway so why bother doing more checks?

We can do that, however, the additional check allows us to return more specific error messages:
"Unknown configuration key: %q" if the key is not known and "%q requires a subkey" if the key is known but missing a subkey. Also, the check is pretty inexpensive computationally since the knownPrefixes slice is only 5 elements.

We always need to check config keys applied to VM's to ensure container-specific prefixed keys are disallowed.
