I have NO IDEA if the rumors I’ve encountered are or are not true, but my understanding is that there are MANY more chumros, and **some of those are of a MUCH more life-changing nature**, than “walking a few steps ahead”.
I would advise DEFINITELY consulting a trusted family Rav, JUST IN CASE it is an issue for this particular potential couple.
May there be many beautiful simchas in Klal Yisrael.
