Microsoft Community Submit idea feature is cool and easy , but some of Microsoft Product Groups still request users to submit their idea through UserVoice. For purpose of integrity, it would be nice to have once place to share all ideas. For this purpose, it is good idea to check with product groups who are using UserVoice for their requirements and features , so you could make it possible they could use this platform to receive idea from users instead of uservoice. In addition, UserVoice is not supporting Microsoft Account and new account should be created which has some new privacy concerns since it is not Microsoft domain.
