>If you think a distro is increasing your support burden it is quite acceptable to tell users from that distro to use the distro's bug tracker.

Sadly, this is in itself adding a large support burden.

I think distributions should be doing a much much much better job of informing their users how they should report issues.

tracker.debian.org seems to be almost impossible to find on google for example (If I search i3-wm debian it's not in the first 5 pages!).
