As far as I understand, there is currently no such “end of term” maturity/redemption envisaged or specified which would make this open ended (“for years to come”) and the assets potentially unretrievable. The suggestion of burning (but only after a certain periode of “vesting” e.g. on year) is essentially a reaction to this and meant to add a further option, a kind of “locking as emergency exit”, though at the price of the holder not realising the possible full NFT value upon maturity. Am wondering whether that could mean that the remaining NFTs’ returns could even increase in the process.
