I too agree.  If we only allow one syntax, I much prefer to stick with
the original, and deal with the punctuation restriction elsewhere.

As far as I can tell, the only actual example we've seen of a key that
ends in punctuation is the one Vaidheeswaran sent, and that still seems
like an edge case to me: it should be corrected by adding data to the
reference database, not accommodated by Org's key syntax.

I think Tom's worry that we might see more of that kind of thing in the
future is fair, and deserves more thought.  I suggest we stick with the
original syntax for now, and revisit the issue in the future if it
becomes clear that there are lots of non-conforming keys `in the wild'.
In the meantime, tools that automatically insert keys from citation
managers can warn the user if they don't conform to the syntax.

Best,
