Hi, it is not obligatory, but we recommend it as a good practice, as it makes it easier to follow the decisions of each delegate. The most important thing we believe is the feedback on the proposals and also the rational of each delegate (it does not necessarily have to be a thread).
It is valid to point out that we need to find a balance in this aspect. We understand that technical proposals may be more complex to comment on, and we do not want the process to become mere formalism or spam. However, we believe that it may be worthwhile to comment on certain technical proposals, which are simpler to understand.
In addition, we believe that if a delegate maintains his or her vote consisting of snapshots and tally, it is not necessary to justify every vote, unless he or she wishes to clarify something. However, should you change your vote, we expect you to provide justification.
We will reflect on the concerns you have raised and work on developing more specific guidelines.
