I think it's an incredibly good idea that should have happened ages ago. SCRA isn't active enough to warrant restricting the indie ID like this. To the point where UN has only ran into SCRA to shoot,RP with, whatever, on any ship, twice?
Let me put it like this: I'd make a Coalition character and log it, if the ID was trans-Sirian again. It'd still be worse than outcast ID, as pointed above.
