Speaking for myself, I haven't seen a list of permissions for Technic from the modders. To be honest, I doubt one exsists. I'm still using Technic anyway, for the sole reason that it would take me hours to go through the mods and install them manually, then correcting the IDs in order to play online with my friends.
If the modpack slowpoke is making is of a higher quality, (which, looking at DW server let's play, is) and is easy to install as Technic, I will without hesitant move to the slowpoke pack.
EDIT: I'll hate it if it's called Feed the Beast modpack though.
