I recently posted a question for a feature-request here on meta, in which I offered a possible solution to a problem (I've deleted the post, since I missed seeing a clear duplicate question). However, the first comment on that post mentioned the XY Problem:
Before someone hauls out the X-Y problem, what problem (use case) are you trying to solve specifically?
Yet it would seem to me that the XY Problem is invalid for any feature-request question.
That is, the [EDIT: now old version of the] feature-request stats on its info (bold added):
Proposals for new features on the Stack Exchange network, or requests for a change to an existing feature.
You have an idea for a new feature to be added, or for a change in existing functionality. Great!
Your question should contain the details of your proposal, including a justification of why the new feature is needed and/or how it can improve the community. Basically, prove to the administration that they should spend time developing your feature.
Yet the XY Problem is generally against the question being about the "proposed" solution:
The XY problem is asking about your attempted solution rather than your actual problem.
Based on the [EDIT: original] tag information, should not the feature-request tag be used in most cases specifically for proposed solutions? And is this not antithetical to issue the XY Problem argues against for most SE questions, and so the XY logic not apply in these cases?
That's not to say that what the XY Problem answer also states:
always include information about a broader picture along with any attempted solution
is still not valid for a feature-request, but based on the [EDIT: original] wording, such tagged questions should have one expecting a proposed solution in them as the focus.
[EDIT: Addendum—while I've clearly had a number of downvotes by people considering this question as not researched/clear/useful, because of this Q & A, the tag information has been updated to be more clear about the fact that a feature-request should still generally not be offering a solution in the question, as much as defining the problem one thinks a solution is needed for; then any solution one has is best put as an answer to one's own question. So while I still do not know why all the negative votes, I'm glad a positive contribution came from this.]
