Maybe I'm misunderstanding the point of lite. If it's supposed to be simple utility mods, as a foundation for making mod packs, then MFR/TE (and jetpacks) seem to be very heavy / big for it.
You're interpreting the point differently.
Its a lightweight pack. It has all the benefits of modded, but feels closer to vanilla. It works on old machines. It can be used as a base to add mods to for personal play or for a small server. It is made from the mods that perform the best on average in various profiling tests.
