Well, actually one *could* run static EtherChannel (A.K.A. 'mode on')
without protocol tunneling. It wouldn't be a good idea (because you
wouldn't catch connectivity problems without the channel negotiation),
but you could.

Oh, and "EtherChannel" is not a protocol, it's just a marketing name
for link aggregation. LACP and PAgP, OTOH, are protocols which can be
used for negotiating forming an EtherChannel.

I agree. Bad idea.
