The page says that extensions should depend on composer/installers to make themselves installable, but doesn’t specify how exactly this should be done. Composer/For extensions#composer.json specifies the version >=1.0.1, which is also found in several extensions “in the wild”, but that results in a warning from composer due to the “unbound version constraint”. composer/installers’ own documentation recommends ~1.0 – any problems with that?
