While I do not think it is possible/reasonable to mandate that all
implementations support encrypted timed text tracks, I also think that it would
be unwise to forbid or discourage CDMs from implementing that feature.

As far as I can tell, the following Q&A is the only mention of timed text in
EME -- the overall architecture appears independent of media type. Can't this
(informative) text be simply removed, and the specification remain silent on
the topic?

"Q: Can I encrypt captions / <track> elements? A: No, this proposal only
supports decrypting audio and video that are part of the media data."
