Comment (by michaelld):

 GR37 and GR38 are broadly binary (ABI) compatible, though there are a few
 very specific differences. That said, the GRC interface is entirely
 different. So, in general we say that GR37 and GR38 aren't compatible, so
 any GR out-of-tree (OOT) should be specific to one version or the other.
 Most OOTs are creating a branch called "maint-3.7" for GR37, and then
 moving master to GR38; for some we'll just have to use a specific commit
 for GR37 & that's the final one. There's no right or wrong; just the way
 it is.
