Issue you tried to resolve in MCPE-169728, created another issue.

Now we can only create 04 items per second, means 16 seconds per stack of items. Even if we hold it, it doesn't let us create a stack instantly. This is time consuming when working on big projects.

I personally create many structures which require me to create stone bricks from stone. This is too slow as I have to get stacks and stacks of them converted one by one now, before it, we can get a whole stack just by long pressing the item.

SOLUTION can be as simple as a setting to switch between Insta craft and single craft, instead of ignoring the community.
