I don't see any reason for changing controls back to old version. After 15h of playing I may say that current implementation is quite convenient, it is faster in one cases and slower in other. One may complain about long tap action which is slower that any key pressing with modifier, but on the other hand, it does not significantly reduce the pace of the game.
Real problem here, and I believe it will be fixed soon, that there is near to zero possibility to order something to Kerfur while it moving lol. Another little nuance raising from new controls system is that you can't put in inventory a thing while having something in hand, it was useful when you, say, working with the shovel.
