Rav Mazuz recently announced an interesting psak. The main part of the psak is actually nothing new, but he did add a couple of factors into it that make it noteworthy for me.

The Sefardi psak in general is that weddings do not include "yichud rooms". The kinyan is made at the chupa and after the couple goes home and has their yichud at home. Rav Mazuz stressed that this is the correct halacha, and so should be in practice.

Rav Mazuz added three points:
1. the yichud room minhag has been forced upon many sefardi communities and that is wrong.
2. the result of the yichud room is pritzus, as he calls it. His explanation is that the friends are hanging around outside the room and commenting and joking about how long they are in yichud for. It seems that this is pritzus. He also adds that it creates a problem as after yichud she would have to cover her hair according to all opinions, and many don't or it is not even realistic to demand that at the wedding, so she goes out to dance and party with her married hair uncovered.
3. Ashkenazim as well should not have a yichud room, according to halacha.

The first point, I agree with (as if he needs my agreement). People should follow their own minhag, until a unified minhag is formed (which isn't going to happen so quickly), and sefardim should not feel pressured by their ashkenazi peers to perform ashkenazi minhagim.

The second point - I don't see it as pritzus, but ok. And there are a lot of opinions as to when a married women has to cover her hair by the wedding - before, during or after. His comment is important, but it is only one of the various opinions.

The third point is unusual an dI did not see a justification for him to say that Ashkenazim should also not have the yichud room. I guess it is because of the pritzus and the hair issue, but, again, each according to his minhag, until a unified minhag is formed.
