forking is a tricky term and the concepts depend on how you define it. hard forks incorporating new innovations are fine as long as they are truly needed and the only effort needed is to download new software. but if it also forces participants to dig out cold wallets and make financial transfers to new coins or new sidechains, that is a big problem. many ppl will get left behind and will lose money.
As Zangelbert Bingledack defined it, existing participants would not need to do anything. They could just sit back with their cold storage coins and see which fork wins out, their ledger position guaranteed.
