Apple has done the best job of creating this expectation.
Apple Feedback = compliments (and ideas)
Public Web = complaints & bug reports
Apple Support = important bug reports (can create feedback first then call immmediately)

Good luck doing that when the bug report (like virtually all bug reports in nature) doesn't provide sufficient reproduction steps.
No, that's not what Apple did. They said, "Please verify this issue with macOS 26.4 beta 4", a very specific version, implying that they actually fixed the bug in that specific beta version (spoiler: they didn't). And I would have to go out of my way to install that specific beta just to "verify" the bug. Moreover, they gave me only 2 weeks to verify before closing the bug that they hadn't responded to at all in 3 years.
They suddenly created artificial urgency for no apparent reason.
Closing bugs automatically after a cron job demanded that the user verify reproducibility for the 11th time: obviously bad.
if the answer is 'everything in that part of the code has been rewritten' or 'yeah, that was a dup, we fixed that' or 'there isn't enough information here to try to reproduce it even if we wanted to' or 'this a feature request that we would never even consider' or some other similar thing, then sure delete it.
otherwise you're just throwing away useful information.
edit: I think this difference of option is due to a cultural difference between (a) the software should be as correct as reasonably possible and (b) if no one is complaining then there isn't a problem
