it means contact tracing becomes easier and lockdowns more effective.
I read that oppositely. If the serial interval is shorter, contact tracers need to work faster to inform those exposed, lest those exposed become infected and transmitting. Likewise, lockdowns would only become more effective if the time each person is contagious is reduced. IIRC the delta variant, according to Indian accounts, is significantly contagious for three weeks from the date of infection as opposed to the usual two.

That would clearly make it harder, yeah. And good point about contact tracing. I guess the only thing that would be easier with a shorter incubation period is isolation after flights and getting down case numbers with a very tight lockdown. Everything else gets harder.
