Query Execution
Description
SERVER-59426 completely disables change stream rewrites for pipelines with a non-simple collation.
SERVER-59659 would eliminate the need for that restriction, but even if that does not turn out to be practical, some rewrites can still be applied in pipelines with non-simple collations.
Fields such as clusterTime, which cannot have a string value, can be rewritten normally. Rewrites for fields that can have arbitrary strings would need to go in a separate $match, which does not get pushed down to the $cursor level of the pipeline.
