Okay, it looks like some family members DID have a problem with it. This is from Flight of the Romanovs, page 345:
In 1961, Prince Nikita Alexandrovich said to Vladimir on his behavior and claim to the throne:
Stop performing this shameful farcial charade!
Romanovs, Nikita argued, had to be called by that name and not Romanovsky, as Vladimir was insisting... the family felt outrage that the Vladimirovichi considered that they were now the only Romanovs, that the family, due to 'improper marriages' had declined dramatically to three...the family believed that they had married no worse than...Kryil and Vladimir themselves.
Nikita also averred that monarchial privileges belonged to all Romanov males as a collectivity. Furthermore, Nikita argued, Vladimir had no right to call his wife and daughter "Grand Duchesses"...Moreover, Vladimir's wife, Leonida, Nikita insisted, had never belonged to a royal family because the Bagration-Mukranaskis had been ordinary subjects of the Russian empire, just like all other noble families.
That's what I thought, and I agree completely with Nikita! If the Bagrations, a deposed house of a country which was now part of the Russian empire, were royalty, then so were the Yussoupovs, who once ruled the Crimea. So why did Irina have to sign away her rights before morgatanically marrying Felix? I am so glad to hear that other Romanovs are upset that their name has been taken away and that the Vladimirovichi claim they are the only ones in the world with the right to the family name!
