Found this while looking back trying to verify some stuff about Chronicles, Some people might find it relevant or at least interesting in regards to timelines and canonicity of games. While this is probably one of the more definitive answers you'll ever get about Chronicles, and something I think I've seen other with similar authority mention, there's also the fact that the statement it's tied to more definitively says "Nothing is canon, until it is." For what it's worth, I've always placed it in my mind to the end of the series just because of the ending if it were to go anywhere, and the fact that it has apparently been 2 years since Eggman's defeat according to the original Nintendo Power reveal, which also interestingly enough calls Central City "Emerald Town". Building off of the "when it's convenient" answer: Almost makes me think the only truly "canon" stories since 2000 have been Adventure 2, Heroes, Shadow, Rush, 06 (as a time loop), Colors, and Lost World. My reasoning for this is that they seem to be the only games introducing characters who seem to be a part of Sonic's current recurring cast of characters. Adventure 2 introduces Shadow and Rouge, Heroes introduces too many to list, Shadow... idk, it doesn't actually introduce anything, but it attempts to give Shadow a new definitive status quo other than "litterally dead" from SA2, Rush introduces Blaze and her dimension, 06 introduces Silver and his constantly ruined state of the future, Colors introduces Wisps, and Lost World introduces Zavok who will no doubt be with us until the end of time, god damn please just let Zeena show up again. Why am I excluding Forces? It has way, way too much storytelling baggage to carry to be relevant ever again without making a direct sequel, Mostly the fact that Eggman nearly definitively won. Infinite is mainly Avatar's antagonist, and Avatar is unlikely to be seen again. It just seems like an excuse to tell the Eggman winning story without ties to the games around it. Mania seems to be a product of it with maybe closer ties to the games "around it" (classic series) but otherwise it's just not practical. Riders games would also be included because it seems like Jet, Wave, and the big one are active recurring cast, but they don't actually show up in anything that's not a spinoff that needs a couple extra characters. I guess my "here's what is likely relevant" timeline would be the original classic games (1,2,3, cd) added to my previous list. But of course, I'd absolutely love to fit together ALL the bullshit.
