      But Windows does allow you to specify things other than the whole subnet, i.e. the whole /24, just like your EdgeRouter does

      You can define more than a /24, but not less.
      In the following pic, you can see the subnet is /24, in the 192.168.100.0 scope.
      The popout is where you define the DHCP scope to be distributed, not the scope of the subnet.

      Be sure not to use "Subnet" and "DHCP Scope" interchangeably like M$ does.
      MS Has you define a scope when you create a new subnet to be served by DHCP, you don't really do anything with the DHCP Scope until you start filling in the Start IP and End IP. No matter how restrictive you make the DHCP Scope (11 to 50 in this case), you will still have a subnet of 255.255.255.0. If you were to make the DHCP scope 192.168.100.1 to 192.168.101.254, you would see the Subnet automatically change to 255.255.254.0

        Exactly - you can definitely declare less than /24

        You can declare anything that's valid for the given CIDR range
        My example shows two scopes with /26 subnet

          Where does it show that?

              I found it, it's in the faded greyed out area under the red rectangle.
