WDYT?

We've been considering doing this for a long time, and I think it's only a matter of time before important libraries needed for standard WF are only compiled to SE 17.

I think WF 35 would be the absolute end of the line for SE 11 support in std WF; after that Jakarta EE and probably our MP impls from smallrye will force a move. 

But I suspect something could easily happen during the WF 35 dev cycle that forces a move, and I think we'd be better off announcing a plan to move on around the team of WF 34 Beta, and then announcing WF 34 is the end for SE 11 when we release the Final.
