Describe the bug
Pretty self-descriptive.Shaped recipies are quite inconvenient for redstone automation.

Expected behavior
It should eat anything in desired quantity disregard of shape.

Additional context
If that's intended behavior, please, make it emit redstone pulse after it finished process.

The decomposer does use shapeless recipes. You can rearrange the items in any shape you want.

Do you perhaps mean that the decomposer shouldn't count the items by separate item stack and instead consider the item count of a Stack as well?
For example instead of needing two separate stacks of honeydew to produce hormone bile instead you just need one stack with a item count of two.

Yes. And there are problems with automatic insertion.
However, that might be surpassed with a bit of redstone fiddling.
If it's intended complecation, that issue might be closed.
