YES, please.

DSP.SE has such a close reason:

This question appears to be homework. Complete answers to homework are off-topic, but specific questions about homework are acceptable if they include enough detail. Please edit the question to include more background about what you don't understand.

(emphasis theirs!)

And honestly, it's the best thing since sliced bread the FFT, because it is a very crisp statement.

Of course, there's the students that in all honesty just want help. And these actually get a positive way forward, and usually start editing¹ and improve the question up to a point of being sensibly reopened or refered to a duplicate. The brutal truth is that thinking about which question to ask is often the solution already.

Then there's those who start to argue "it's not homework, I just randomly came across this totally constructed example", "I just want an answer", "if you can't help, don't put down other people's questions"; and you can just ignore these, they are exactly the type of volunteer time bloodsuckers you don't want to encourage.

Problem

SE has this problem that it's kinda inflexible. You can only have a limited number of close reasons. So we'd need to decide which one has to go.

Personally, I'd just merge the "usage" and "repair" close reasons, but that probably warrants a larger discussion.

¹ ok, that paints a bit of an overly positive picture; many skip the "please edit your question", and just starts commenting, but it's a good start.

Problem

We can only have a limited number of close reasons, three. So we'd need to decide which one has to go, or ask for an additional slot.
