R&S Example page/ISSNs suggested on verified magazine records?

I've just noticed on the verification help page that it suggests that the ISSN can be placed in the ISBN/catalog number field of magazine records. Has there ever been a conclusion to discussions about whether the ISSN should be recorded in the database records at all? The last I recall was that the ISSN could be recorded on the magazine's Wiki page, but not necessarily to each of the issue records. If this is true, perhaps the verification help page should be changed. Thanks. MHHutchins 15:43, 29 July 2009 (UTC)
 * And to bring up another issue, can't the software be changed so that this empty field on magazine records would not generate a Bibliographic Warning? Just like the warning has been suppressed on pre-1950 pubs (which I think should be extended to at least 1965.) MHHutchins 15:48, 29 July 2009 (UTC)
 * That should be changed -- the last time this was discussed the consensus was, IIRC, that ISSNs should b recorded in magazine wiki pages, but not in the Cat No/ISBN field, because they change rarely if ever, and so don't distinguish individual magazine issues. -DES Talk 15:52, 29 July 2009 (UTC)

 * The last discussion started out as a discussion of how they should be entered at which time it was suggested that they should not be entered at all.--swfritter 15:58, 29 July 2009 (UTC)
