Thanks for the list, fennster!
Well, the reason to remove them from the inventory would be to automatically *) free space for new and actually useful materials.
Or is there any reason to keep them?
*) Not every player is active in the forum and learns about the change.
I didn't mean there is no reason to, I mean there is no reason they will. I could be wrong they might just remove the commodities outright.
It's kind of the nature of engineers at the moment really. Without using third party apps/websites you just don't know.
Even the items that can be used, might not ever be used.
As an example Anomalous FSD telemetry is only used in one blueprint, long range interdictor. You could carry 100 of them around and never need them. There are many others.
