Could the core team clarify what will happen to the unmerged 6.0 PRs?

Hello there

So Rails 6.0 beta 2 has just been released.

Could the core team clarify what will happen to those unmerged PRs in the milestone?

https://github.com/rails/rails/milestone/63

I am among one of the PR author, having my PR already been reviewed by two core team members.

Given that the PR is huge and has taken a year, I have concern it would not make into 6.0.

Any communication would be very appreciated. Thanks.

Mark
