The FlagsUsed contains a list of flags that were used, which allows the classic (non-buildkit) builder in dockerd to produce an error when non-supported options are used in a Dockerfile. This is a short-term solution; a more permanent solution will be to keep track of which version of the Dockerfile syntax is supported, and to have the classic builder pass the maximum supported version of the syntax.
