Slightly related... how about em0.100 type nodes?

# ngctl list
There are 3 total nodes:
  Name: em0             Type: ether           ID: 00000001   Num hooks: 0
  Name: em1             Type: ether           ID: 00000002   Num hooks: 0
  Name: ngctl48803      Type: socket          ID: 00000005   Num hooks: 0
door.dino.sk# ifconfig em0.100 create
door.dino.sk# ngctl list
There are 4 total nodes:
  Name: <unnamed>       Type: ether           ID: 00000006   Num hooks: 0
  Name: em0             Type: ether           ID: 00000001   Num hooks: 0
  Name: em1             Type: ether           ID: 00000002   Num hooks: 0
  Name: ngctl49103      Type: socket          ID: 00000007   Num hooks: 0

It looks like the dot in interface name is not handled gracefully here...
