We could do that in >> =E2=80=98core-updates=E2=80=99 now. I'm not too found of it. It'll make the already slow Guile build much slower, making the lower strata of core-updates packages more painfully slow to build and test. It'll also enable us to overlook the issue for years to come (similarly to the fact that the testsuite of the Guix package itself hasn't been run in parallel for the last 6 years or so :-)). It also won't fix the issue of Guix modules compiled in parallel suffering from the same problem. So I'd keep it as it is for now, as a reminder that this is a serious problem in need of a fix.
