Description of Linked Ticket

The following commands are user-facing but specify {strict: false} for how they parse their input. This means if the operator misspells an argument to the commands or includes a non-existing one, they won't always get an error. Changing these commands to be {strict: true} would protect against this but should be weighed against driver's and/or server's ability to send these commands internally without needing to know which version of the server they are talking with.
