He’s good for us (3)

I believe the answer is:

gus

'he's' is the definition.

'good for us' is the wordplay.
'good for' becomes 'g' (I've seen this in other clues).
'g'+'us'='GUS'

(Other definitions for gus that I've seen before include "Augustus (dim.)" , "T. S. Eliot's theatre cat" .)

I've seen this clue in the Evening Standard.
