Unfortunately, replay protection as defined is that it requires all
software to upgrade - miners, wallets, applications, etc.  It's a hard
enough problem just the get overwhelming miner support.  Getting
overwhelming support from every application on the chain is a much
different scenario.  Further, since we know some software is old and not
being updated, we know for a fact that users of that software, with replay
protection, will be stranded.

Our goal with segwit2x is to get massive miner support.  We'll see if we
get there.  But if we do get 95+% support, its a better scenario than the
very large chain split caused by requiring all application software to
upgrade.
