Your easy dismissal of the necessity the need for SMB1 or an acceptable substitute is annoying. Some of us work for small businesses that nonetheless have multiple locations and subnets and are stuck with old software that when browsing to find data on the network needs SMB1. It's also just too convenient to give up the ability to browse to a system on the network to check if everything seems to be OK with it when it's at another location that has another subnet so our intracompany gateway-to-gateway VPN will work properly. People who completely dismiss the validity of this viewpoint seem to me to have no idea of the variety of small business environments that aren't large, don't have large budgets, but still are a domain network.
