Reference lists are constantly being proposed for deletion. They don't
seem to be well-liked in "(main)", nor in "Wikipedia:" (largely
administrative), and would be warping "Portal:" from the current usage.
Yet, anybody with familiarity of an actual paper encyclopedia knows
that reference lists are encyclopedic. The solution over at Wiktionary
appears to be adding an Appendix: namespace for reference lists, about
6 months ago.
