concerns re PIE migration

As I understand it, the PIE is being migrated to some new platform and we have been asked to comment on any posts marked "Feedback Review Window" to indicate that we want particular activities to be migrated. Does this mean that anything marked as "Not Planned" will not be migrated? If not, this is an issue for me.
Over the past few years, I have been actively championing a number of PIE items, many of which have been marked as "Not Planned" by moderators for reasons that, in my mind, have not been satisfactorily explained. Removal of these ideas going forward is unfair and does not acknowledge the extensive time and energy that has gone into creating, nurturing, and developing them. One that is particularly important to me (and 244 others) is:
BrightSpace quizzes in need of critical updates (D9656)
Submitted: 10/20/2022
Vote Count: 244
Status: Not Planned
* there are also EXTENSIVE and valuable conversation threads between PIE members on the idea. This is evidence of true "Community" on the PIE and losing this in the move to a new plaform is unacceptable.
Also, at the risk of being lost in the migration of the PIE, anything that has to do with linking the Attendance function to the gradebook, such as:
Attendance: Associate a Grade Item with an Attendance Register to export attendance scores to Grade (D222)
Submitted: 07/31/2013
Vote Count: 345
Status: Not Planned
Lastly, I want to draw attention to an item called Spend an Entire Year, Only Fixing Bugs (D10413). Despite being well-intentioned and raising important issues, this post appears to have been unilaterally hidden by moderators with no explanation. If you want us to meaningfully engage the PIE, this sort of heavy-handed moderation is unacceptable and cannot be allowed to continue in the PIE's next incarnation. This is what I see when I try to load this post now:
Also unacceptable is the following rationale for closing PIE D10253: "I am closing this idea since our team of Ux Designers would not appreciate it." This is not a reason. Favourable or unfavourable, community members need to feel that their contributions are welcomed when posting to the PIE.
