I might even go a step farther - you shouldn't care. It's the equivalent of caring whether or not your generated HTML or compiled IL or Assembly "looks nice."

If the SQL is performant and it returns the expected data, that is good enough for 99.9% of cases.

There are cases where you have to care, e.g. the difference between AsSingleQuery() and AsSplitQuery() in EF Core. This option only affects what kind of queries EF Core will create to perform the same job, but it can have pretty significant implications on performance in some cases, and it can affect the consistency guarantees you get for your results.

The abstraction is great, until it breaks.

In this case, with ORMS, even good ones, this happens often enough in production that to actually master the tool you do need to care.
