The impetus for this driver feature request is to proactively report any incompatible matches of driver/mongodb pairs (https://docs.mongodb.com/ecosystem/drivers/driver-compatibility-reference/).

For example, if Java driver v3.11 had baked in a mongod/mongos compat version 4.2 at the time of writing. Then the driver would log a warning when connecting to a future v4.4+, thereby flagging the potential incompatibility and encouraging the user to upgrade.

Optionally, you could also add a warning for a min compat version for the language/runtime.
