Well, no, not NOW as in right this minute, but something should be decided before the fund gets too large IMO, at which point it could become a very contentious "hot potato".

A simple solution would be to just donate it to DAO, at which point the stakeholders can decide what to do with it.

However, that requires some careful rules because donating to the DAO would turn it back into SBD and boost the ratio, which could undo what was accomplished up to that point (especially if the fund has become large). Probably need to wait until the ratio is low enough with some safety margin, and then donate.
