Has the effectiveness of fever screening declined?

On March 6th, jimrandomh predicted that the effectiveness of fever-screening for coronavirus would decline, because the virus would evolve to produce fever later or not at all. Has this happened in countries that have been liberally applying fever-screening?

It was never effective, due to the long incubation period and wide dispersion in symptom severity from person to person.

There are few enough viral generations in this pandemic and few enough mutations in any given branch now and few enough fever screenings in their histories that there literally cannot have been a decline overall.
