I think ... and this is just a guess ... that some might be taking the approach of "there's no code compliant device available, so the rule ought not be enforced." There is some justice in theat argument.
The 2008 code also placed sundry restrictions on the use of MWBC's. It's almost as if they wanted to ban the practice - without saying so. If so, they are being dishonest .... and KNOW they've exceeded their mandate.
November is fast approaching. Get those proposals in!
