Sorry for this! We all make mistakes; both normal users and sysops. If a template 'foo' used inside the category keys [[category:blabla|... {{foo}} ...]] at pages 'bar' 'foobar' etc. is deleted and category membership would be updated automatically as a consequence of Bug 4857: Page purge queue daemon (for template updates, etc) 'bar' 'foobar' etc. will not be membes of 'category:blabla' any more. If such "mistakes" should be detected a special page 'Brokencategorykeys' is needed. Maybe other mechanisms should be available alternatively / as well: a) indications while deleting templates that the category is used in 'category sort keys'; but if these indications are ignored? b) disabeleing the detion of such templates unless they are removed from all relevant pages; identifying these pages would be a painfull job c) others? best regards reinhardt [[user:gangleri]]
*note* Comment 0 does neither cover the general case when links (wikilinks or external links) are broken because of deleted templates in contructs as [[<namespace>:foo{{bar}}]], [protocol://foo{{bar}} foobar] etc. nor because of missing / unspecified parameters of the used templates. Identifying such broken links in the main namespace would have a higher priority then listing unspecified parameters in nested templates.
Hm. Well, if a user relies upon a template to set membership and/or sort key, one would hope they knew the repurcussions of changes to it.
Using templates, magic words, etc. to set sort keys doesn't make them "broken". Regardless, this is the sort of task suited to the toolserver, since it's an infrequent, low-audience feature.
