Yes, it is Okay. It is just that it would be better otherwise. As many things in life.
I would like to see that change. We should propose that something is added to the introduction to the site asking to avoid questions with how to.
Advantage? I see it will give askers a tendency to solve what they want before asking and solve what is X and Y instead of leaving to the responder what it is they want to do.
"How can I fix?" is not referring to the tools to be used
"Can this Y be set to X?" Tends to go to the point
