How to settle the dispute of the Oxford comma?

The battle of the Oxford comma is caused by the double roles played by comma in English. One is to separate a noun and its non-restrictive appositive, the other to separate items in a list. Then confusion arises when it is ambiguous which role a comma is playing. The solution is therefore obvious: rid of one of the roles and assign it to another punctuation. Which role to rid of is also obvious: separation between items in a list, of course, because the other role of comma, separation between a noun and its non-restrictive appositive, is the single most device in English that facilitates precision and clarity without breaking the flow of a sentence. The only question is To which punctuation should we assign the role of separating items in a list? I doubt such a punctuation exists in English, unfortunately.

So we need to borrow from others, say from Chinese. In abandoning the terse, elegant classic written form for the wordy, clumsy “plainly colloquial” (白話文) form of written Chinese, the Chinese scholars about a century ago did create something good out of their cultural destruction: they introduced punctuations to Chinese. As an instance of technological leapfrogging, not only did they adopt the punctuations from the West, they also invented a new one: the pause “、”, signifying a pause shorter than what a comma does, and separating items in a list. Thus a Trump-voter can write unambiguously “the talk show featured Trump、a conman、a clown” instead of “the talk show featured Trump, a conman, and a clown” (sounding as if Trump is a conman with the Oxford comma) or “the talk show featured Trump, a conman and a clown” (as if Trump is not only a conman but also a clown without the Oxford comma).

The only problem is Qwerty. In order to generate the pause “、” in Mac, I need to go to System Preferences, select “Language & Region” and add “Chinese” to my Keyboard Preferences; and in the midst of typing, I need to switch the language input from English to Chinese and hit the backslash key to produce a “、”. Thus, chances are that the battle continues despite existence of an obvious solution.
