Media applications have to support devices with non-updating web frameworks that are as many as 5 years old. So applications won't be able to completely give up on MediaSource.isTypeSupported for quite some time.
If there's a warning, it would only show up on newer devices and evergreen browsers, though, so that should be fine and probably won't cause much confusion.
It may not be possible to deprecate the isTypeSupported() API, but maybe we can encourage user agents to display a warning and also discourage further specify these capabilities for media elements and instead use w3c.github.io/media-capabilities/.
