Well, then you should switch your mind to the solution
using netgraph. ;-)
Anyway -- You asked "what is the major reason double vlan
support is still not included", and the answer simply is:
1. It _is_ included (only in a way different from what
you were thinking -- but nevertheless, it _is_ there).
2. The major reason that nobody has implemented a way to
do it with ifconfig (like you proposed), is probably
the fact that there's already a different way (using
netgraph). So nobody was motivated to implement yet
another way to do it, I guess.
If you don't like to do it with netgraph, I suggest you
write some patches and submit them with send-pr(1).
If the patches are good, they will certainly get committed.
Best regards
Oliver
