What is a reasonable justification for CQRS's read model sometimes being intentionally DENORMALIZED (containing some duplicated/pre-joined data), even though this would typically be considered poor practice in a traditional normalized relational database design?

What is a reasonable justification for CQRS's read model sometimes being intentionally DENORMALIZED (containing some duplicated/pre-joined data), even though this would typically be considered poor practice in a traditional normalized relational database design?
What is a "command handler" in a CQRS implementation, and what is its typical responsibility?
What is a reasonable way "eventual consistency" relates to a CQRS implementation where the read model is updated ASYNCHRONOUSLY after a write occurs on the command side?
What is a common motivation for adopting CQRS, particularly for a system with significantly different READ and WRITE requirements (e.g. very high read volume but comparatively rare, complex writes)?
What is a reasonable justification for a team specifically evaluating whether their system's read and write REQUIREMENTS are genuinely different enough to warrant CQRS, as a key question to answer before adopting the pattern?
What is a reasonable way a message queue or event bus is often used to connect the write side and read side in an asynchronous CQRS implementation?
What is a reasonable way the "Command-Query Separation" (CQS) principle -- an older, more general object-oriented design principle -- relates to CQRS specifically as an architectural pattern?
What is a "query handler" in a CQRS implementation, and how does its responsibility typically differ from a command handler's?
What is a reasonable way CQRS can specifically help with SCALING a system's read and write capacity INDEPENDENTLY of each other, as one commonly cited operational benefit of the pattern?
What is a reasonable justification for a team choosing to apply CQRS SELECTIVELY -- to just one particularly complex or high-traffic part of a larger system -- rather than applying it uniformly across the ENTIRE application?
What is a reasonable characterization of the ADDED COMPLEXITY that adopting CQRS typically introduces, compared to a simpler, traditional single-model CRUD architecture?
What is the relationship between CQRS and Event Sourcing, given that the two patterns are frequently mentioned together (though they are technically distinct, separable concepts)?
