I think allowing them is possible, as long as \end{equation} ends the
last line (with trailing whitespaces tolerated).

I assume that, for simplicity, PLACEHOLDER could be longer than one
line, too.

If Bastien agrees and if you want to provide a patch, please be sure to
include tests in test-org-element.el, and appropriate changes to "Org
Syntax" document. The manual may need to be updated, too.
