It wasn't temporarily retasked, it was reorganized and permanently repurposed and renamed the US DOGE Service, and then within that reorganized service, a subordinate temporary organization was created called the US DOGE Service Temporary Organization that was scheduled to sunset not later than July 4, 2026. (All but 65 of USDS's pre-reorg employees were also fired as part of the reorg, and 21 of those remaining 65 employees did a mass resignation.)

If you visit their website, you will notice that except for historical documents, there is no full name branding at all; mostly only the logo and the occasional "USDS", when prior to the reorg (as can be seen on the Wayback machine) the original full name was prominent.
