No, they just made it harder by adding in this clause:
You have to sell up lock, stock in the UK and have everything in the other EU country. Close your bank accounts, sell your properties.the centre of [the British citizen]’s life has transferred to the EEA State where [the British citizen] resided as a worker or self-employed person.
They can't close Surinder Singh down entirely without having major changes made to EU law, but they can make it bloody difficult.
they did this to:
The stupid of penalising your own citizens for nothing more than marrying a foreigner just goes straight over their fat heads.… preventing abuse by those British citizens who move temporarily to another member state in order to circumvent the requirements of the usual immigration rules for their family members upon return to the UK
No doubt they will then argue that having moved the centre of your life to another country you no longer have ties to the uk and so have no reason to move your family there.
