One could go semi-auto only without too great a penalty but there is a need for very, very rare full auto fire. Some ambush situations, breaking contact, CQB in buildings and the like. Not always in those examples but sometimes...
For combat, better to have a capability that one may use rarely than to not have it when one might need it. In this case, given little additional complexity, small to no weight increase (other than ammo usage...) ease of manufacture and such, there is no significant burden attached to the weapon. The training requirement is increased but only slightly.
Using semi-auto only weapons is essentially a technological cover for inadequate training. The full-auto problems of lack of accuracy and excessive ammo expenditure are obviated by better training. Thus the weapon should not be the issue, training should be. All things considered, best to keep the capability and train better.
