[Temp Check][Social] Adding ProposalBond to ENS Governor to make proposing more accessible

Hey Kent, check out the notes from last week’s meeting here for context. Essentially, the social proposal technically did not meet quorum, and so another social vote is warranted.

If this is the case and there are no changes to the codebase, I presume we wouldn’t need an executable vote (correct me if I am mistaken).

Looking forward to hearing about your new approach to implementing this bond mechanism to lower the threshold for submitting executable proposals!
