In principle I agree with you, and I upvoted your proposal.
In practice, I'm worried about how we could ensure uniformity of treatment between different disciplines, when people might not understand the potential generality of a certain relatively technical question related to a certain field (e.g., questions pertaining the relationships between, say, engineering and mathematics)where to draw the line of technical but not-too-technical.
Will we be spending time reminding people, in comments or here in meta, that certain questions are on topic?
Just to give an example from the recent past, several people would vote to close questions about writing style and formatting. These are somehow technical questions related to what is clearly a major activity of ours. How can we ensure uniformity of views with more borderline questions?
