I can see documenting this being useful, but this is pretty far into "quick-start has way too much in it"

yes. I have the same opinion as @aojea . #572 (comment)

we should first thing how do we want to reorganize the docs, seems that they are starting to grow and I think that adding an advanced section with this stuff is not a good solution because we are going to have the same problem after some time.

in addition to this PR, I see that we have some documentation on how to use kind in CI or some extra advanced features, which may need to be reorganized.

kind in CI is now in the resources doc

I also don't think this is safe to enable in kind. it can evict the core images.

so I forgot to follow up here but I've followed up more with SIG-node about this.

currently kubernetes has a gap in this -- airgapped images that are sideloaded (like kind's) are image-gc unsafe.

we should provide a different option, I will think on it some more, but this is too much of a footgun for users.
