I never slammed any minhag. You and others seem to need to respond overly aggressively to litterally anything...
Either way, I am actually not saying that the Shar hatzion applies to kosher min of haddasim that happen to be shotim.. but if someone asked if there are "any" veiws that there is a chashas basl tosif, yes there are plenty of reshonim and achronim who express concern, especially and primarily when the extra hadasim are not kosher..
1. Which shar hatzioyon?
2. Many rishonim and achronim hold many things, and SHULCHAN ARUCH along with POSKIM (nosei keilim, s"a harav, mishna berura etc) are the ones that PASKEN halacha. They were not too concerned....
Just to put things in perspective: the Ravad held that it's okay to say that hashem has a body....
3. Study a bit of Jewish literature, specifically on the subject of "minhag", and it's holiness.
4. Siddur mahari kopel and shu"t avnei tzedek discuss taking 9 hadasim, the Kolbo writes about 68/69 hadasim!!!!!
