Compare also Willie's feedback here that this is perfectly legitimate, at least in his eyes.
However, when I flagged this question for possible transfer to cross-validated, as I consider it a much better fit there, it was declined with the I believe auto-generated feedback "declined - vote to close as off-topic," which I read as meaning that instead of suggesting questions for transfer, I should instead vote to close them.
Note that my question is not a(nother) request to transfer the specific question, nor do I ask as the refusal irks me particularly. It is a procedural question as the feedback sounds as if transfers are discouraged. Is that so?
Edit: On re-reading my own question, while the feedback sounded auto-generated, it might have been typed out as is by a moderator who might have a preference against transfers, which is well within his rights. If this is the case, I would rather delete my question as it could be (wrongly) perceived as personal, when it is meant merely procedural, for the general, not specific case.
