Well, it's all changed now. When the Test & Go scheme resumes (applications open on Feb. 1, they say), travelers will have to have an official first and second test in an approved SHA-Plus hotel, with booking of room on both Day 1 (arrival day) and on Day 5, and wait for the 2nd test result before checking out or mingling in public areas. I was required to remain in my albeit very comfortable room before getting the arrival test result at about 6:30 AM.
