On a slightly different subject. Over several months I have gathered some 500 medical abbreviations. Where would they fit ? In wikipedia ? In the Wiktionary ? Or in a stand-alone abbreviation Wiktionary ?

Certainly a Wikipedia page (or set of pages) with the list would be useful. Also, I have found it useful to make subject-specific jargon words subpages of the subject, which makes them easy to use as ad hoc links in other subpages without interfering with top-level pages. See, for example, the Wikipedia "poker" pages. This might not work as well for abbreviations, though, since they may not be used for ad hoc links as much (one presumes that most Wikipedia texts on medical subjects will use unabbreviated terms since there are no space limitations). 0
