given that switching to the new version is "relatively easy" after 
install too, in both directions, I would conservatively keep using 
FFSv2  as default, but suggesting EA for new installation without 
interoperability issues, for this release.
If all goes well, for the next release, which would be 11, or even 10.1 
(debatable) switch EA on.

Given, however, that ufs2ea-flip exists, I don't find it that menacing 
to switch to EA by default.
