✋ Current vendor positions on Web MIDI API standardization & implementation

• Mozilla: The Web MIDI API RFP position is still uncertain, primarily due to inherent security vulnerabilities that could be introduced by bringing SysEx messaging into the web.
• Microsoft: After receiving developer feedback with over 1000 votes, the Web MIDI API is currently not in the implementation roadmap for Microsoft Edge, Desktop, Mixed Reality, Mobile, or Xbox.
