I think the similarity is as follows:
- there is a desire to fix something that feels like a gap (in this case limited support of constant-time math in standard library)
- there is a change proposal coming from the community
- there are arguments why it should be included and some discussion if it belongs in a separate library or not
- very little or no input from core team
- the whole process is stalled waiting for core team to participate
Now we just need someone on the core team decide they need to research via implementation instead of actively engaging community, end up liking their own solution more and we'll have dep all over again.
