The issue was Nicholas II refused to approve Grand Dukes marrying outside the Pauline Law. On that point, he was adamant.
But that surely was a very political issue - the Romanows are not that old a family and the scandals surrounding them were impressive - from Peter the Great marrying a kitchen maid to Catherine the Great killing off her husband and then there's the paternity question of tsar Paul... The Romanows reigned more through the sheer force of their power and their political cunning when it came to dealings with their bojars than through legitimist issues like eg the Hanovers reigned in the UK. During their reign of Russia the Romanows saw the ancient kingdom of France go down the drain and they saw the nationalist movement change the face of Germany but they saw as well how secure their direct neighbors, the Habsburgs, had formed their empire on marrying. So surely for the tsars after Paul Royal marriages were not something that had to do with prestige or keeping their blood clean, but of political alliances. Thus they married their Grand Duchesses in as many Royal houses as they could find but were careful not to "socialise" too much with their own nobility (which had weakened the power of the monarch eg in the UK).
The Imperial House Statue aka the Pauline laws were made as much as other constitutional ukases to secure the reign of the Romanows. There simply was no other way for the Romanows during the times when they actually ruled. They couldn't have discussions about the status of their male dynasts, they couldn't have relatives from a Russian mother's side taking part in their political game.
But after the revolution this changed. Then a marriage to a princess Bagration was no political problem anymore and the Head of the House could decide to declare her as equal. I mean, only some years ago Dr. Otto Habsburg, current Head of the family of Habsburg-Lothringen, declared a commoner as "ebenbürtig" (equal) on her marriage into the family. The same happened in the Wittelsbach-family, when princess Kathrin Beatrix (formerly Miss Wiegand) was declared equal after close to 20 years of marriage, because the Wittelsbach have needed her firstborn son with prince Luitpold as their future Head of the family and so the current Head granted the young prince the right to succession on declaring the marriage of his parents as in accord with the House law.
House laws need to be changed sometimes if they should still fulfill their raison d'etre, they were there to guarantee the survival and the power of a noble family and when times are changing, they have to be adjusted. See the Sayn-Wittgenstein-Berleburg-case, where the family goes against the stipulations of the will of a former Head of the House, who decreed that only noble and Aryan women are eligible for marriage. While queen Margarete of Denmark as aunt of prince Gustav could easily ennoble his intended, she can't make the girl into an "Aryan" - thus the house laws need to be changed in order to be according to current laws. The time of Racial laws in Germany is over for such a long time, thank God!
So what's good for the Habsburg or the Wittelsbach (or the Windsors with a future queen Camilla) should be good for the present day Romanows as well, IMHO.
