I’ve put a bit of information together about each of these new proposals and collated them on this post, with a few more observations and questions → Subnet Management - General Discussion - Governance / NNS proposal discussions - Internet Computer Developer Forum (dfinity.org)
On a side note...
@dsharifi, would you consider providing a link to the relevant forum discussion in proposal summaries in the future? 
This is super useful as it allows voters in the NNS dapp to know where to turn for critical discussion and debate relating to the proposals (allowing them to cast a more considered vote).
As an example, ‘Change Subnet Membership’ proposals have recently started providing a link in the proposal summary to the relevant subnet thread on this forum (thanks again @Sat), e.g. 132225, 132228. :)<
Update I’ve revisited via the dashboard and noticed that the URL field is provided and links to this topic 
(I was initially looking for this in the proposal summary). It doesn’t look like the NNS dapp renders this URL when viewed on a mobile device (but this is arguably one of the most important pieces of information for voters who wish to make an informed decision).
