RE: how does EME/DRM effect captioning

This discussion appears to hinge on the validity and importance of use cases where captioning value warrants DRM, and also on whether the need is sufficient that it must be accommodated in the first release of EME.  I personally don't know if this is a hypothetical need or a real one, but my instinct is that that clear captioning is more than sufficient, and a technically simpler model as well.

Seems to me this is the optimal approach.

1.)	Minimizes any potential barriers for users
2.)	Benefits service providers by supporting open ansillary
services, like indexing.

Am I wrong? Is there any actual use case for encrypting captions? What did I miss here?
