Thanks for this feedback!
I think at the moment there is not much more clarification that I can provide, rather than stating that this is probably not feasible for the initial version of SNS governance canister that is also discussed here.
But as already stated in my other answers, it is valuable to get the feedback that there is some need for this, so that we can take this into account when prioritising next steps.
Also, in case you have particular use cases in mind for minting / burning, I would be happy to learn those!
