I have several dust pools that I never joined, are just filling space in /pools, and that I cannot even remove (thus send/sell).
As you can see they are not bonded, but if I try to “Remove Liquidity” I either get an error or nothing happens (cause I guess the shares are very low?).
Having a toggle on the UI would be a quick fix, but as an investor I would like a long term & efficient solution, ie. to erase them from state if possible (like anything under 1$). A common solution other chains adopt, which is mainly an anti-spam measure, I think is having existential deposits, which in this case would transalte to existential pool shares, ie. an amount under which the asset is nulled.
