If one searches the JUCE codebase for “some platforms” one finds 17 instances where a feature or function is claimed to work on some platforms but not on others, but either no further information is given, or the information is incomplete.
Such information is quite vital, why not include it? It would be best to provide information which is as explicit as possible. Otherwise we are forced to guess or dig in the codebase for an answer which is obviously already known to the JUCE team.
