There are many obscure ways to bypass the effects of starshards and rapidly boost industry, which makes starshards problematic. Starshards have become one of the main ways to skip spiraling.
I'll explain the simplest reasoning with stoneaxe's
When a stared Stone Axe mines out quarrys arts, the quarrys arts will not gain the stared effect unlike all rocks and ore mined with a stoneaxe normally, also stoneaxes -20% effect don't apply to quarry arts.
The start of the process is using any size of starshard on a stoneaxe (boosting its quaility by 1 to 4 for small starshards). Use the now stared stoneaxe to mine quarry arts (quarry arts does not get starred) and you split one block to get sticks (gets the stared effect).
craft new stoneaxe with the new quarry arts + stared stick and the result is a un-stared stone-axe better axe. Now repeat the process to easily spiral stone-axe.
The splitting of the block is what boost the Q beyond the quarry arts nodes.
Beyond the simple:
If you use 50% non-stars resources+ 50% stared resources, the outcome is always a nonstared object or tools.
This effectually ruined any typically grinding method and favors abusing starshards to push industry.
Starshards should be removed or changed how they work. instead of boosting quality have them boost the stats of the items instead.
