So the list of Svardik Adolim that insist that Svardim should not have yukla at the wedding is long and impressive.

Rav Ezra Atiyah in the Tshuvos Yaskel Avdi, Chalik Zayin Avnezer Simen Yud, Rav Vadi Yosef in Yechav Adas, Chalik Hei Simen Samach Bez, Rav Ben Sion Abba Shaul is quoted as well, saying the same thing, the Maimor Mordechai, Rav Mordechai Elio in his Tshuvos Maimor Mordechai, Chalik Bez Avnezer Simen Vav, Rav David Halevi in the Tshuvos HaSeil HaRav, Chalik Dal Simen Unhei,

Rav Meisas, all these Sephardic Adolim say that they should continue with the Sephardic tradition.

Rav Yitzchak Yosef wrote an article in the Torah journal Tchumen in the 31st edition of Tchumen.

where he says that it's a breach of tznius, to have a chassan and kala go into a room alone, with everybody watching, and the whole world is going to dance into this room, and then they're going to go into a room all alone and lock the door behind them.

What kind of tznius is that?

Everyone knows that they're going into a room in privacy.

That's not appropriate.

That's probably his idea.

It's probably that it's an extension of what the Gemara in Kisubas tells us, that everybody knows,

what's going to happen on the night of a wedding.

Someone who speaks about such things, someone who tries to focus on such things, even if he has a gzardin of 70 good years for speaking about such things, the gzardin is going to change to 70 bad years.

So Rabbi Yitzchak Yosef thinks it's just inappropriate that this is going to be something that's done in such a public way.

Now one could argue on the flip side,

that, no, they're going into a room together, and everybody knows they're not going to be having Tashmish, because they're coming out ten minutes later, and they have a wedding to celebrate.

Everybody knows that they just want to spend some time together before they go, and celebrate with all the guests.

And that does not seem to be at all a breach of Tzinias.

But anyway, that's the argument, one of the arguments Yitzchak Yosef makes.

The stronger argument, and the one that is more prevalent,

is that the reason that Sephardim don't do Yichud at the wedding is because, because it completes the Nisuin.
