Agreed, it is not a requirement for the activity to implement portrait
layout.  When it is not implemented, part of the activity would be
invisible after rotation.  The learner will rapidly find the activity
does not work well when rotated, and will avoid rotating.

Sounds good, please propose a design and patch.
