The change to make whips no longer bless-able and so that you cannot lose them is quite a big one IMO and I am quite okay with working that way.
I strongly think at least some of the whips curses need to be tweaked to keep the balance though.
Especially looking at the "one-shot" curses like Lightning whip.
It is a very punishing curse for a very strong whip which made sense before since you would get rid of that curse once you blessed the whip.
The Ice Whip on the other hand which is about as good as the Lightning Whip (not trying to start a debate which is better) works the other way around. The curse is fair and a challenge when you first get it because it changes the game's mechanics. However the more you play with it the more you learn how to use that to your advantage and for a fair amount of players (especially the experienced ones) it becomes more of a blessing instead of a curse.
I do not want the Icy Feet to be changed. I do want Glass Bones to be nerfed though.
