As best I know, the varions "old style" tamper / child resistant covers are still perfectly fine, and UL continues to list them- as ordinary covers. Let's not confuse the recall of one product with any form of 'lost listing' rumor.
The advent of the new 'tamper resistant' standards did not do anything to ban previous versions; it's just clear from the NEC text that such covers and inserts will not meet the NEC requirements for 'tamper resistant.'
So, where might one be able to "legally" use such covers and inserts? Simply put: in existing installations, or to fulfill requirements from some source other than the NEC.
An example that comes to mind is for meeting the county requirements for home-based child-care businesses.
Here's a little UL humor: UL is very generous in distributing all manner of "swag." That is, things like pens, notebooks, flashlights, etc., with the UL logo on them. Some years ago, they were distributing very nice inserts (plastic things to stick in receptacles so that kiddies couldn't poke a paperclip in) with the UL logo. Much to the chagrin of UL, it turned out that the inserts were NOT made of any material that UL had evaluated for such a purpose. Imagine: UL was actually distributing 'counterfeit' products itself! OOPS.
