The matrix definition functionality is deprecated. We should update our config to use the generate.tasks command instead, as is recommended by the Evergreen documentation.

As part of this work, we should consider slimming down the number of tasks included in our configuration. A few reductions to consider:

• compression doesn't necessarily need to be tested as a full axis. We could run a subset of tasks (or tests) against a small subset of server version/topologies verifying the driver adheres to the compression protocols properly, but its not necessary run against all versions and all topologies
• The DBX testing matrix policy says that NoAuth NoSSL variants only need to test a single MongoDB version + topology combination
