Culling obsolete pages on wiki.debian.org

This is a follow-up to https://lists.debian.org/debian-doc/2021/09/msg00018.html, in which Popescu referred a  question about obsolete wiki content to the -www mailing list (which I personally don't think is quite right because the wiki is supposed to be documentation).

Agreeing with Kesper (https://lists.debian.org/debian-doc/2021/09/msg00009.html) much of the wiki is badly outdated and clashes with other documentation (such as that in /usr/share/doc , the handbooks, mailing lists, stackexchange, etc.). A lot of it should be removed since it will just frustrate new users and lead to more traffic on -users as people ask why a squeeze (or earlier) tutorial doesn't work on their system.

Anticipating "So do it yourself, then," response,  before I open a wiki.debian.org account and start slashing and burning obsolete content, I'd be grateful for some guidance on the diplomatic way to remove or update obsolete information without offending people.

I would also like the list's thoughts on whether this matter should be referred back to debian-doc to work on a coherent documentation strategy that makes it easier to maintain. No sense in fixing everything to 2022 standards if it will be obsolete again in 2025.
