Honestly, I think we should take the Nova defaults (which will flip to
v2 shortly) and move forward. v1 usage in Nova will be deprecated in a
week. It will default to v2 for people in Newton and they will have to
manually change it to go back. And because we did the copy / paste
approach instead of common dynamic code, the chances for a v1 regression
that is not caught by our unit tests is very very small. It's basically
And we're going to delete the v1 code paths entirely in September. By
the time anyone deploys the Newton code the master v1 code will be
deleted. And our answer is going to be move to v2 for everyone.
It doesn't make sense to me to drive up the complexity by testing both
paths. We'll have a new tested opinionated default that we lead with.
