As far as I can see it is consistent with the LPPL if *-tex engines have a modified input path that picks up a modified inputenc.sty, so long as any modifified packages, in the words of LPPL > clearly and unambiguously identifies itself as a modified version So there is no need for the base packages to have explict reference to experimental engines, but also no need for packages that are known to fail on those engines being loaded by default.
