Mainly in that maintaining it can become an issue... also, if you exceed a certain size it won't be indexed, so you'll have to reference other sitemap files, and/or generate them.  I've found you're far better off ensuring only the recent endpoints that are updated since the last google scan are about best.  And even then, google (and bing) will do a good job at natural discovery.  The sitemap really only allows for those sites with frequent publication to be checked more often by google.  If you are doing less than a couple posts a day, there's very little reason to worry about it.
