The shut Zevchai Ztedek, Orach Chayim 27 - explains the SA that everyone should taste as only referring to when they have their own cup, but there is no need to drink from the main kiddush cup

שו"ת זבחי צדק חלק אורח חיים סימן כז

הרי בהדיא שדין זה שכתב מרן דמצוה מן המובחר שיטעמו כולם הוא מקורו מן הרא"ש ז"ל והרא"ש ז"ל בהדיא כתב שיש לכל א' וא' כוס בידו

However if there is only the one kiddush cup then because of a love for the mitzvah you drink from it.

דצריך לשתות מכוס המברך אפי' אחר ששתה הוא ממנו משום חבוב מצוה

So at least it is a source to drink for the love of the mitzvah - but still it is from the cup of blessing!
