Even just not shaving on the Rashbi's yahrtzeit, is certainly praiseworthy. I always found it ironic that the day is associated with shaving.
The day is associated with the "end" of the practical ramifications of sefira (for those that hold so). Shaving is a result.
Similar to the end of the 3 weeks, I always found it funny how in camp there was a count down to chatzos on 10 Av and then boom, the music is blasting as if at that moment everything never happened and all is jolly again.
