Two reasons:
1) I have found that the game runs better with the core rules only*, and maybe a very small set of carefully-chosen supplements. If the core does not include the right mix of classes, that creates big problems for the campaign.
2) When publishing expansion material, WotC cannot rely on customers owning anything beyond the original core set. As a result, for sales reasons, the material that is not in that set will not receive anything close to the same level of support as that which is in that set. Witness the level of Psionics support in 3.5e - yes, there is a little beyond the XPH, but there's not much. That's the level of support we can expect for the Bard, Sorcerer, Monk, Druid, and any other class that's missing.
* Where "core rules only" means the first PHB/DMG/MM.
