Yungerman: See the Nodah Bihudah O.C. 1:14, I think. I shave often (2, 3 times a week) during the year. But I always shave Friday before Shabbos. It’s a lack of Kavod Shabbos to have the scraggly startings of a beard that I will get red of as soon as possible. Kavod Shabbos is a Din D’rabannan (maybe D’Oraisa to some Rishonim). Not shaving is a Minhag. The D’rabannan wins. My only remedy would be to decide to grow a full beard and just start it now, something that I am not really wiling to do.
I don’t really have a problem with being clean-shaven every Shabbos during Sefirah. I do it every year. Just this week, I’m going to be a guest somewhere where I’ll probably be the only one clean-shaven. I don’t really mind that either, I’m just worried that some Kanoi will misread the Shulchan Aruch and attempt to embarrass me publicly for this. It’s not quite Lifnei Iveir on my part, but it’s probably not a good idea.
