They could accept your gun and install the new competition trigger, would that work? Maybe factory warranty an application of a hot iron and bit of Dremel touch up.
John_AZ hit the nail on the head. When you have the largest aftermart support of any pistol manufacturer (with the possible exception of the 1911 makers), why spend money to compete with them.
Glock's business model is to provide a simple, reliable product for agency use. That product also works well as a canvas for personal/defensive/competition use. Individual users and the aftermarket handle that end of it.
