Thanks for the response. To clarify, burning DECs is akin to increased ownership.
For example, if you have 1% of DECs, and then 50% is burned, you will now have 2%.
However, I can understand if you only own SPS, moving it to the DAO could be considered to be more beneficial especially in the short term as DECs are out of circulation (thus increasing the need to burn SPS), but also within the DAO so by staking SPS you have some level of control over it. However, once a DAO votes to spend it, the DECs are either back in circulation or burned. If it's back in circulation, the need to burn SPS is again gone and if the DECs are burned, it's effectively the same as this proposal.
