Oh it is that time of the year again.
If we could upgrade resources like this, you wouldn't have any reason to explore or colonize other worlds.
I will agree somewhat however, I have in the past suggested a new tool bonus that simply increase the quality of the resulting product by a little bit. Raising the quality of a production output by 5 or 10 wouldn't totally break everything. And there are already nice tool effect indicators and functionally, so it should be easy to implement.
This would also lead nicely into my suggestion of making more advanced tools that are required for advanced resource extraction and manufacturing.
