I certainly won’t argue that supporting Scouts is our primary purpose - and Scoutbook is specifically designed to support that - as a unit and district leader I have often wished we had better adult tools.
As you say, many service and training awards are self-initiated, and many folks are perhaps too modest (or unaware) to pursue them themselves. But as a leader of leaders, it’s important to recognize the service/support our volunteers provide to keep this movement going, and it would be great to have more tools that provided information about registration history and previous awards to make sure folks are being properly recognized (i.e. thanked) for their service.
I personally wish more folks would earn the Training and Key awards, because that would mean we have more trained and experienced leaders around. And if unit leaders had more insight into the progress towards those awards their volunteers are making, perhaps they could help push them along the trail, and perhaps even recognize their volunteers without them even having to submit the paperwork.
So, yeah, while I don’t want Scoutbook for leaders, I also kinda do.
