[HIP] Re-assign forfeited unvested grants and staking rewards & make unvested token grants and staking rewards un-expirable

The title of this post has been updated to “[HIP]”.

Given that this is the second Temp Check passed under the new process, wanted to give more guidance on how it works from here on out (you can reference this article):

b. This forum post should remain open for minimum of 3 days before a final vote is submitted (to give time for others in the community to review and share their feedback as well)
c. Author reviews/incorporate new input/feedback that are applicable
d. Guardians have been notified to review and approve/veto this HIP
e. This HIP will need majority approval from the Guardians before it can be submitted by community for final vote - the Guardians will reply to this thread directly.

Thanks!
