@AAQ
this lack of attention you refer too , has duly been noted by the gaon the avnei nezer zatsal
at the end of his tshuvot on YD where he concludes that the shavuot do not apply lehalacha
cf avnei nezer YD 454: 49-51
satmar rave takes issue with his opinion in vayoel moshe
so this is a machloket between those rabanim
