No one requiring doctor's appointment? OK with some reservations (3,4,4)

Ross

I believe the answer is:

all very well

'ok with some reservations' is the definition.
('it's all very well, but...')

I cannot understand how the rest of the clue works.

(Other definitions for all very well that I've seen before include "Everyone's fit" , "make an ironic objection" , "no one ill?" , "Phrase often introducing an objection" , "that's fine as far as it goes" .)

I've seen this clue in The Guardian.
