It wouldn't be beyond what the Government to consider it, but like we have been talking about, we suspect the Government is going to embrace it, with their strange intreptations and try to move anyone who isn't clearly economic or family onto that track, like UK Ancestry, Single Mother and anyone else they want to force into an excruciating 10 year wait.
They can't fully eliminate a path to Citizenship as that would easily contravene Article 8 and Article 12 of the ECHR.
