For example, if you configure languge version 2.3 and api version 2.1, consumers would need to use Kotlin 2.2.0 or newer to compile code using your library, and would need to provide Kotlin standard library 2.1.0 or newer at runtime to run it.

On other platform LV/AV don't affect compatibility, you always need to be at least same major version (i.e. 2.2.20 vs 2.2 is fine, but 2.3 vs 2.2.20 is not).
There is an initiaive on proper support of LV - KT-76131. Not sure if we should mention it, as it's now a bit shelved.
