Is there any preview of the libsmi-based dissection available? I'm
curious/concerned how it will handle e.g.

- explicit-length and implicit-length index strings
- display hints

I'd be extremely unhappy to lose any of these features, but I can't see
how oid/name/type-restricted flat files could offer them.

Additionally, I've already got my MIB collection configured in/for
net-snmp and current Wireshark can happily re-use it automatically (e.g.
by setting MIBS to "ALL"). The libsmi approach OTOH would require
additional configuration work for me every time I change my MIB collection.
