This will probably not come for quite some time.

It will not be done.

It will not be done.

This implies parachains won't be able to use Babe as block production engine and need to stick to AuRa or a custom implementation, correct? I would be super interested in some arguments for this decision if you have the time. Thank you!

I guess we just need a new issue support sassafras?

[bkchr]

As @xlc already pointed out, Sassafras will be the one that will be supported. Not doing BABE is mainly a decision to not waste time. I mean when Sassafras comes, it will be superior to BABE. So, no one will probably switch to BABE knowing that Sassafras will come.

I guess we just need a new issue support sassafras?

This will hopefully directly be part of the implementation of Sassafras, aka support for Parachains.
