Unfortunately the procurement PR campaign focused on selling it to people who will never use it, instead of selling it to those who will use it. Unanswered questions created doubts. Hopefully it will prove to be everything predicted and more. But there remains the issue of answering what will fill the gap in dismounted ops when a 60 would have been carried but a AGM cannot be brought within manning and operational limitations, or the question of semi-indirect and indirect applications of fire into dead ground the AGM munitions cannot reach where a 60 would have succeeded. Perhaps if we had a better conceptual model of the infantry platoon as a fighting system, within which support weapons are one component, then any future was developments can be shown to be effective within the system model and that could have mitigated some of the internal PR damage.
But, to be fair, we've never effectively studied the section or platoon as a fighting system - a balance of manning, weapons, mobility, etc. - and created a capability baseline we wish to maintain, accepting decreases in one capability component when offset by an advantage elsewhere. Instead, for procurement purposes, we try to argue the validity of swapping out individual items one for one, and failing to show the mitigating elements within the organizational system where shortfalls are perceived.
