The main point seems to be "I don't like it". If you consider this a
strong argument against the concrete issues with the functional API,
then good for you.

This is not true. The pickling restrictions which have been raised are
specifically caused by the functional syntax, something which your
warning omits.

This is not bikeshedding since it addresses concrete functional issues.
(but apparently you would very much like to sweep those issues under
the carpet in the name of "bikeshedding")
