As seen from "why-use-bee-honey-on-rosh-hashana", the use of bee honey in the minhag is clearly circumstantial - the lack of "the original" honey led to use its substitute - bee honey.
Some background: the Land of Israel is known/blessed with "milk and honey", where honey refers specifically to dates (earliest I can find is Mishna Bikurim 1.3) but see also Yerushalmi Bikurim 2b:
ודבש אלו התמרים. יכול דבש ממש? רבי תנחומא בשם רבי יצחק ב"ר לעזר כתיב (דברי הימים ב ל״א:ה׳) וכפרוץ הדבר הרבו בני ישראל ראשית דגן תירוש ויצהר ודבש. ודבש חייב במעשרות. אלא אלו התמרים שהן חייבין במעשרות.
Once we have plenty of the original date honey, did anybody offer/switch to using date honey to signify and remember the honor of Eretz Israel (maybe a sort of "Leshana Haba'ah B'Yirushalayim")?
