Why is Miles and Gwen viewed differently than other Superhero romances?

I recently saw a comment saying how the reaction to Miles and Gwen compared to other romances is a bit interesting. I wanted to hear people's thoughts on it.

Mostly every single superhero film has the main character having a love interest with them becoming official at the end of the first movie. It happens all the time and you do not see people complain about it.

However, with Spider-verse you had people talking about how they did not want romance in these films. People point out how the first film did something new and original and kept the main boy and main girl as friends. But I felt it was pretty obvious that they were going to expand on that more.

I think it is even weirder because every single Spider-Man film deals with some sort of romance. Every Spider-Man story deals with different types of love and it is pretty important for the character. Why did some want Miles to be the one without romance?

You even have people saying Miles and Gwen are forced despite not even being together yet. And that they should just stay friends despite the two wanting to be together.

It is worse because the romance parts of the Spider-verse are pretty plot-integral compared to other generic romances that happen for tropes.

Why the sudden double standard?
