Seems like a petty disagreement to me, not big enough to separate God’s family for so long. I used to go to liturgy committee meetings when I was a church musician, in high school and college. One reason I never became a full-time professional was that I couldn’t stand bickering over what was going to be done, in what way, and when, when there were much bigger fish to fry— like saving souls.
This is not petty, as the position of the priest projects a particular understanding of his role. Note that the Orthodox do not attempt to dictate to the West elements of the Latin liturgy at all: the use of a particular language, the text of the prayers, the manner of preparing and receiving the Eucharist, how to do the sign of the cross, etc., even though on all these things our rites differ.
