One of the main functions of the brass case is to transfer heat out of the weapon, something that it does very well. Caseless ammo doesn't offer the "disposable heat sinks" like metallic cases do, and one of the main problems with the G11 ammo was cook-offs.
The metallic cartridge is near-perfect for its job, and that's why cartridge technology has hit a plateau: there's simply nothing out there that does the job better. Caseless ammo has size and weight advantages over metal-cased ammo, but it comes with its won set of inherent problems, and those outweigh its potential benefits. Otherwise every major military in the world would be fielding caseless small arms ammunition by now.
