All common parameters that have to do with streams follow a two-letter alias format (first letter of the stream name followed by the first letter of "Action" or "Variable"). In fact, -InformationVariable has an alias of iv. So why does -InformationAction break the mold with an alias of infa instead of simply using ia as an alias? I couldn't find any competing ia alias in common parameters.

This issue should be addressed by adding ia as a secondary alias for the -InformationAction common parameter.
