You are right it could be done as suggested.

As  I replied to Thomas this result in strange behaviour of the menu. 
When selecting/deselecting one of the python entry the menu do not 
handle properly the "circular reference" and it's almost unusable.

No. All the package that don't support python3 have in their Config.in a 
line like this: depends on BR2_PACKAGE_PYTHON
The same way potential package that support only python3 could have: 
depends on BR2_PACKAGE_PYTHON3
