But it looks like some "web-security best practices seminar" somewhere
has begun to "teach" that allowing pasting is a security issue.  The
question is, how do we stop it before it grows too far?

Not unreasonable, but if the password reset subsystem is sufficiently
easy to use, also not really an issue to be too concerned about
overall.

If you read down into the article, the blocking of paste operations is
driven by javascript.  Without javascript turned on, pasting still
works properly.
