Atifah is a chiyuv? I thought it was minhag to make a point of wearing
a four cornered garment during tefillah.

One might argue that a minhag to be yosheiv uboteil from some mitzvah
makhsheres or qiyumis (an asei that's not an imperitive) is a minhag
shtus, but I didn't take that for granted. Clearly the MB felt that
without the "derashah", it would be very strange.

Tir'u baTov!
