Is there a way we can show the deprecated warning in command help?

Is there a way we can show the deprecated warning in command help?

actually, using the MarkDeprecated() method from pflag explicitly removes the flag from any help or usage messages from now on, which makes sense because we don't really want anyone using this flag from here on out. this will only show up for people who are already using the flag.

That is strange. The command help docs did not change in this PR.
