I like to hear diminished over the A section a la Charlie Christian and Sonny Stitt, and so on. Mainly, jazz guitarists need some cool diminished licks. ;-)I have got a fair collection of diminished melodies - stolen from the internet, or from Slonimsky, or transcribed, but am still searching for the definitive diminished lick book. Know of one?
Bruce Saunders' Diminished Workbook is very comprehensive.
