# validation, there was a bug on server versions 4.2.0 - 4.2.5 where
# the server would accept the commitQuorum option and use it internally
# (see SERVER-47193). As a result, the drivers specifications require
# drivers to perform validation and raise an error when the commitQuorum
# option is passed to servers that don't support it.
