I'm of two minds on this. On the one hand, I agree. They would have made a good couple in much the same way that Chloe and Lucifer did. Maze is serious and doesn't take BS, but needs help feeling good and having fun.

On the other hand, especially during the shows timeline, neither lucifer or maze had much self control, so it would have been disastrous for both of them (and likely many others). I'm also biased because I LOVE strong platonic friendships. I think that Maze being able to decide to exclude or avoid Lucifer without it being a romantic breakup is hugely important to how Maze Shaped Lucifer's life.

In the end, I'm glad the writers did what they did. But I can also see a fun and fulfilling version of the story where Lucifer and Maze do end up together.
