I'm not sure about mages or other caster DPS but any class that deal heavily in instant casts or DoTs, like shadow priests, will probably see fairly small returns to haste as well.

Shadowpriests can spam:
Mind Blast (1.5 casting time, CD 5.5 - 8 depend on how heavyly you specced in imp mb)
Shadow Word Death (instant, 12 sec CD)
Shadow Word Pain (intsant, DoT over 18 -21 -24 (depend on spec))
Mind Flay (channeled, 3 seconds)
Vampiric Touch (1.5 casting time, DoT over 15 sec)
Vampiric Embrace (instant, last 60 seconds)
As you can see MB suffer from the GCD problem, like scorch, but it's on a quite long CD, SWD has a long CD too, SWP usually need to be recast every 24 seconds (who would not put 2/2 in imp swp?). VT is something like MB, but on a longer "CD".
Considering a 5/5 Imp MB, 2/2 Imp SWP and, of course, 1/1 VT we have (ideal case: no latency and immediate human response):
0.00.00 VT
0.01.50 SWP
0.03.00 VE
0.04.50 SWD
0.06.00 MB
0.07.50 MF
0.10.50 MF
0.13.50 MB
0.15.00 VT
0.16.50 SWD
0.18.00 MF
0.21.00 MB
0.22.50 MF
0.25.50 SWP
0.27.00 MB
0.28.50 SWD
0.30.00 VT
0.31.50 MF
0.34.50 MB
0.36.00 MF
0.39.00 MF

MF has been cast 10 times, which means a total of 30 seconds over 60 seconds fight spent channeling. For sure there are classes which benefits more than shadowpriests from spell haste, and probably +damage is still the best stat to agument their dps, but still, i wouldn't say that spell haste gives small returns to shadowpriests.
For what concern affliction warlocks, having 4 dots (2 instant, 2 with 1.5 casting time) plus an instant curse, probably 2/2 Nightfall, and some time spent using Life Tap / Dark Pact, probably the effect of spellhaste is a lot less noticable. I agree on this point.
P.S. Assumptions
1) Haste do not affect GCD (otherway MB and VT would be also positively affected, resulting in only VE, SWD and SWP not being affected by spellhaste)
2) Shadowpriest goes all out, otherway it would be more MF and less SWD/MB, meaning more time spent channeling (so more benefit from spellhaste)
