I'm with you here and would even not add a simple stylesheet. People adding simply a guestbook won't use Cocoon, so it's more or less useless effort. Cocoon Forms has "higher aims" :-)
Sorry if I misunderstood you, but your sentence on "focusing on server side form processing" is the only thing I take issue with. As for the rest, I'm happy that we fully agree.
Cheers,
Ugo
