Yes, 'block-start' and 'block-end' seems like viable alternatives. If
so, do we also need 'before' and 'after' as aliases? Although the cost
of an alias is quite low, there is still a cost.

One issue may be with the 'top-bottom' and 'bottom-top' keywords
(which were added in response to a use case described in [1]). If we
simply expand the keywords, we would get:

  top-bottom = block-start-block-end
  bottom-top = block-end-block-start

Which is longer, and perhaps not so intuitive.
