Bob, I feel you're very rude and I'm really upset.

You're just dropping the subsystem you didn't do anything without any consensus
from who are contriubting lots of patches to make it works well for a long time.
I understand you want to merge zram/zswap to remove the concern Mel suggested
but so your intention might help the community. But the approach was totally wrong.
You just said a few days ago in my thread and I was holiday so I didn't have
a time to reply all of the mail sent to me. Should I break my holiday for
just replying to you? Are you okay that someone else removes or moves your efforts
without any consensus with you while you're spending good time with family?

Please be careful. Bob.
