This last >> point, I believe, is crucial. I think there were several issues we discussed: 1. We can only approximate that actual profile content; storing an approximate =E2=80=98manifest.scm=E2=80=99 along with the profile w= ould IMO be deceptive. 2. It=E2=80=99s easy to maintain compatibility over a data format, but it= =E2=80=99s much harder to maintain compatibility for code. I think we discussed these issues the best we could in the megathread, so I=E2=80=99m personally in favor of moving forward in a pragmatic way. Thanks, Ludo=E2=80=99.
