[Development] Should the system proxies default setting be switched to true?

+1 for switching to using the system proxy settings by default.

I'm still a bit wary about the 'Windows issue' though. To cite our documentation [1]:

  "On Windows platforms, this function may take several seconds to execute depending on the configuration of the user's system."

Was that the problem with Windows versions configured for automatically querying for PAC files, but never getting any response?
