The default speed feels very sluggish in my opinion. I can understand a slight delay to prevent multiple scrolls at once but the previous value felt more like an arbitrary limitation that did not improve the quality of the game. I haven't heard any complaints about the length of delay being proposed here even with at least a year of testing from different communities.
If there's a problem with this change such as something technical I would not mind creating a convar and adding a menu option to allow a custom setting so that the few negatively impacted by this new delay won't suffer. I haven't encountered anyone like that however.
