Yeah. Just have the workers find some silver along the way instead...

Or buff them to actually be worth something. +1

Update the value don't remove them.

Addressing your edit.

I realize it's only a little bit of silver, but last time I sold everything it was in excess of 100m silver.  If they update the price on it, it would actually be a decent way to save and hide the silver from  yourself.  The problem is when the trash values changed years ago they never updated the trash value of excavation nodes.  It only recently became an issue because of the ability to ship a node to an alternate storage, at most it took up 2 slots in a storage that likely had 9 to spare, now they take up 16 slots and you don't have the room to spare, or rather you don't think you have the room to spare.  If  you properly set up your worker node you will have the room to spare in fact you will likely have 100+ more slots that you didn't have before the change 2 months ago.

well they want to clean up the game a bit because they get alot of feedback that there are too many different items in the game and this would be a good start.
Now if you have all the excavation nodes you will get 23 different trash items taking storage spaces, which might lead to either spend pearls or contribution points for more storage space.
You could use those contribution points on better things than some trash items.
It also feels bad for people who organize their storages to have items in there which have no use.
So there are a few options to make it better than it is now:
* delete the trash items (not a big loss in terms of silver especially after introducion of Sacks)

* increase the value but at the same time maybe make it 1 trash item instead of 23 different ones.

* just change it to extra silver.
