For me the question is what a user expects when its applying LIMIT. The fact
we don't (yet) support it is less relevant in that context. Is there anything
on LIMIT in the SQL standards?

The harm I see is that we have two options to achieve apparently the same
result, which could also be conflicting with each other ("What output can I
expect when I set `number-of-rows` to 10 and `LIMIT 5`")?
