Its not going to be an in-protocol problem. Let's say you refuse to be involved with the swap. You have two options, sell your STEEM now or watch what happens to the value of your STEEM when all the exchanges delist your STEEM for his TRC20 tokens.

The only way we could get decent liquidity for Steem Classic is if we built a bridge to Ethereum so that Classic STEEM could exist in Uniswap.
Blocktrades and steem-engine got us covered.
