Given the goal of the stack is to make an "universal database", I'm wondering about one point: the arrival of LinkGlide/CUES changes a kind of "rule" in terms of compatibility, which invalidates the "universal character" of many answers. Given we are speaking here about a transmission system that is meant to replace the entry level of Shimano, it's not unreasonable to assume that it will be widespread - I wouldn't ask the question if it were Microshift, for instance (Microshift will probably loose momentum as CUES will generalise).
This answer for instance is not universally right if considering the LinkGlide/CUES range.
For reference, what LinkGlide/CUES changes is: there is one chain type for the whole system (an 11-speed one), but the system is offered in 9, 10 or 11 speeds. But the pitch between sprockets remain the same, an 9-speed LG cassette can be considered an 11-speed LG cassette with the larger sprockets removed (the position of the smaller sprockets relative to the center of the bike are the same, the larger sprockets are added close to the center). So all answers that state that a 9-speed cassette must be paired with a 9-speed chain. Same for cable pull and pull-ratios for derailleurs.
Shimano has published a guide to highlight the differences between CUES and other ranges: https://si.shimano.com/en/cues/technical-assets-tips
The least effort solution I'd see would be to add a notice for questions marked with specific tags and older than a given date, would it be possible?
