Research direction
Start by running the two data.table examples in the issue with verbose output and compare their GForce paths. Trace the handling of by = .EACHI in the grouping and join code; done means the first example can use GForce while preserving the expected result and existing behavior.

Description
data.table(a = 1:2, v = 1:2)[.(a = 1L), min(v), by = .EACHI, on="a", verbose=TRUE]
#Making each group and running j (GForce FALSE) ...
data.table(a = 1:2, v = 1:2)[a == 1L, min(v), by = "a", verbose=TRUE]
#Making each group and running j (GForce TRUE)
