Require smaller components to reset?
For example, going from version 1.2.3 to 2.2.3 is fine. I think if you bump a component, all of the smaller components should reset to 0. That means 1.x.y becomes 2.0.0.
I had a need where 0.1.x.y and 0.2.x.z have almost same API except single breaking change in API: former had own FromJSONKey and latter used aeson-1. As mentioned in the other issue, we don't connect "smaller-bigger" with "older-newer", it gives us flexibility.
This actually would break the compliance of packages that adopt yyyy.mm.dd versioning, and simply don't release major versions more frequently than once a month.
This fell sharply out of favor, but we wound up with a bunch of stupidly high 3000.xx version numbers as a result of folks trying to recover from its prevalence in our community for a while.
It is a good convention to adopt that you should reset (or, as i'm partial to doing, completely omit) minor versions, but it seems an awkward requirement.
For the record, transformers-compat has something like the same issue @phadej mentioned.
In my case I have to ship multiple patch releases with different flags to allow it to package selection to properly backtrack on older versions of cabal. Otherwise, the package simply can't automatically select the right flags.
So whenever I ship a new version I ship x.y.z.2, x.y.z.3, x.y.z.4 for transformers 2, 3 and 4 compatibility, respectively and it'll get worse with additional transformers versions.
