after you increased the delay of the crafter and the copper lamp, many mechanisms stopped working.  It is not entirely clear why you considered it a mistake that they have a delay less than other blocks. 

In the error MC-265910, the person pointed out that Crafter should not be able to craft every game tick (by the way, he could not. he needed 1 tick for crafting and 1 for waiting)  does not agree with Dispensers and Droppers. But why should the crafter, in principle, be consistent with these blocks in redstone?

The bottom line is that after this "fix", a million mechanisms broke down for people, since the mechanics of these two blocks with such a long delay are meaningless in redstone. and there are ALREADY videos and guides on these mechanisms. And because of this innovation, a person will be misled, because of this change. The players liked these blocks just the same because they do not look like existing redstone blocks and give new opportunities. Now, due to a VERY LONG delay of 4 (I may be wrong) ticks Crafter and Copper Bulb have lost a lot of functions and meaning from these blocks now as much as from poisoned potatoes.
