You have an interesting idea, but it seems tricky to pull off in practice. To be clear, I'm not necessarily trying to say that low effort issues _are_ a waste of my time, but rather, that is sometimes how _I feel_. I think it would be good to collectively reduce their occurrence---I'm not sure how---but sometimes the choice isn't between "low effort issue" and "high quality issue," but rather, "low effort issue" and "none at all." In the latter case, I'm not sure which I would prefer. Certainly, sometimes low effort issues really do lead to productive outcomes.
It's tough and it's not something that has an easy answer. Some part of it is me overcoming how negatively I feel about them and another part is perhaps others spending a bit more time filing good issues. At least, in my opinion anyway!
