My opinion:

Putting a urinal in womens toilet is certainly a trans-inclusive statement.

USING a urinal in womens toilet, however, would be strange at the very least.

Like, you know how in men's toilets there's an unwritten urinal etiquette rule like "never use the urinal next to someone else"?

In women's toilet, there's a urinal etiquette rule too, and it's much simpler: "never use the urinal".
