[New-bugs-announce] [issue42650] Can people use dest=argparse.SUPPRESS in custom Action classes?

[Brad Warren]

New submission from Brad Warren <bradmwarren at gmail.com>:

argparse internally sets dest=SUPPRESS in action classes like _HelpAction and _VersionAction to prevent an attribute from being created for that option on the resulting namespace.

Can users creating custom Action classes also use this functionality without worrying about it suddenly breaking in a new version of Python? If so, can we document this functionality? I'd be happy to submit a PR.
