What happens if many like me just keep running core v28?
If more than 55% of miners start supporting BIP110, your node will be happy. You will be on a BIP110 chain, but it's a soft fork, meaning your node is already compatible with it, and won't be upset.
If fewer than 45% of miners start supporting BIP110, your node will be happy. You will be on a chain without BIP110, and things will be just as they are now. This is the scenario I think is most likely.
If miners are deeply divided, then I'm not sure what will happen exactly, but your node should be happy either way: if BIP110 wins, your node will be happy because it's already compatible with it, and if BIP110 loses, your node will be happy because nothing changed.
