Comment 7 for bug 1954470

> As an aside, I seem to recall backports not being done to the Server Guide, which can mislead readers. Keeping a single set would sidestep that issue.

IMHO, given the limited amount of editor attention the server guide gets currently, it would be better to annotate the specific places where it's known that there are per-LTS differences, and keep a single set active only. Otherwise the old LTS guide will just rot. Better to have something that is generally up-to-date for older LTSes with possible omissions when there's something version specific (that we can fix when asked) than have an immediately out-of-date guide for older LTSes.

I think this method is particularly applicable here because generally everything in the guide is written retrospectively.
