Exactly. That's a good reason for being very conservative with the Turtle grammar. We know what we have now works for people, and we know that N3 and RDF/XML (for example) don't.

Just because I don't write Turtle by hand very often doesn't mean other people shouldn't.

Though, to be honest I think we (RDF users) either are past that point, or should be. Writing HTML by hand went out of fashion rather quickly when the web took off, but it was critical to getting it there. IMHO.
