It is wide agreement on the fact that freezing precipitation is very dangerous to any aircraft type.
How it is handled is depending on the type and the operator. Most airlines I know allow flying into light freezing drizzle and fog. It goes into good airmanship and experience how far you want to apply that. But it is wise to be careful.
When ATC reports that FZDZ is over, the crew was happy and continued the approach. Makes sense.
I see a minus in front of your FZDR title in your thread, so I might assume that it was light?
