It's in the current 11.3 beta, strange it's not in the release notes...
if its not there, that means its gonna get pulled last minute :(

But to be fair, they better make it as bug-free as possible like AFPS migration.

Can foresee people losing precious messages history and making a huge fuss

Messages in the cloud is something that would be horribly bad if it went wrong even slightly.

Give Apple time to get it right. Believe me, if they released it half baked people would be bitching even more.

For something that uses Apple's servers, working in beta does not translate to working in production. We're talking a couple orders of magnitude more users in production than on the beta.

Look how long the beta period was for iCloud Photo Library. They'll work it out, just give them time. You really don't want to rush this. Imagine the frustration of all your devices being out of sync, missing messages, and so on.

I was told 11.3 includes iMessage in iCloud but it's disabled/hidden for non-Apple employees. Could be that they're applying finishing touches and add it via a minor update or enable it server-sided later down the line.
