John -

I agree that the fuse may be deleted from the product on the
basis it is not required for safety compliance.  It's
ultimately the decision of my customer to accept or reject
any such advice.

Since the fuse is operator replaceable, I do not expect that
marking as you represented below, will meet the requirements
of the standard, since the intent is to use more plain
language than that.
