Right now the EF Core Provider has no way to specifically request MQL for a LINQ expression.

This has caused some problems most significantly the inability for us to cache the MQL for a given query.

Additionally it blocks two more EF features we want to implement:

• Bulk update operations in EF9
• Partial filter creation in CreateIndex

Outside of EF we could also use this as a way to provide compiled queries directly in the MongoDB C# Driver.
