   This statement is absolutely correct: "- apache-airflow requires Python ~=3.6, so it will not be satisfied for Python >=4.0" . Presumably python 4.0 will contain some breaking changes  (no-one knows for sure as it is not even planned), yet Python 3.6+ is really supposed to be backwards compatible, so barring some dependencies (that prevent us from 3.10 support) it also supports all 3.6+ versions. 
   
   The specification ~3.6 is correctly describing this statement (it means "support any 3.x version above 3.6". I think the message from Poetry is quite wrong. You should silence it, or even better - the project that has >= 3.7 should be corrected, because >= 3.7 is pretty wrong and it SHOULD be changed to ~3.7. 
   
   No-one knows what is the scope of the Python 4.0 except tha it will be a breaking release when it comes, so stating that project will work for it is for sure wrong.
