More input on this issue:

'cmdoption' is a directive, while 'option' is inline markup. Therefore I
wouldn't say they're completely similar, just meant for different purposes.
Both a directive and inline markup is useful for describing "official python
executable options/flags". Regarding per-module options, I'm not sure
special markup is needed at all. So a policy has to be define regarding the
correct usage of these directives/markups, and probably documented in
Doc/documenting/markup.rst
