Phase 1: Stop exposing Web MIDI API to insecure origins from Chrome 77. Phase 2: Prompt users for permission always. Web MIDI use is classified into two groups, one is non-privilege use, and the other is privilege use with sysex permission. Today, only the latter use prompts users for permission. For better security, we will change this behavior to prompt permission always regardless of sysex use. This change is planned for Chrome 82, but the plan may be changed.
