Good note! Worded another way (just to drive the point, for folks new to CTEs), using a CTE means you’re restricting what the query planner can do.

WITH queries are sleek, but not a silver bullet.

Absolutely. But it’s important to keep in mind that CTE’s are optimization fences. Optimizations like predicate pushdown are not currently available. More complicated queries may benefit from being rewritten with subqueries.
