Don’t shoot me!
I think the itch Roy Thomas wanted to scratch was the itch to write about the characters he read as a little kid. So he wanted them to be faithful to those comics as much as possible.
Of course, a lot had been done with those characters and their world by the time Roy had the chance to use them, so he had to work within those parameters. But he spent a lot of time rearranging the furniture, so he didn’t always agree with the changes others had made and pushed to make the world fit his childhood experience.
There’s no question that original Alan Scott had a lot of affairs with women. And that’s the Alan that Roy wrote. If you stretch it you can say he’s bisexual, but never came out in the comics. However, bi people get a bad rap from both the straight and gay community and I’m not sure another self-denying bi character is what we need.
I mean, sure, all DC books are now in another reality and you can do some revisionist history to populate the past with kinder, gentler people. But it doesn’t scratch my itch to read about characters who are faithful to the original comics. Just because there’s a new continuity that shouldn’t have the effect of making all previous continuities off limits. That’s a recipe for polarizing the fanbase.
Now, there are plenty of vintage characters where it seems like they were possibly LGBTQ and you could have stories about them. I wish we could have that.
