This post asks a good question. I am wondering if we should migrate it to EL&U SE though, it seems like too specific of a grammar question for our site. I am asking here on Meta, so as I gradually unlock new privileges I would be able to vote for closure with confidence in my knowledge over grammar questions like this one.
An ELU mod writes (on the suitability of the question for ELU):
While discrete questions of grammar are probably more suited to ELU than writers, in this particular case the question would probably end up rejected by being closed.
Using asyndeton [omitting all ands in a list] or polysyndeton [putting and between all elements in a list] is not really a matter of grammar. It's a stylistic treatment, and both forms have recognised names which your OP knows and uses. It makes no difference how the list is introduced or formatted; a list is a list. Whether it's laid out as in the question, or set out as bullet points, and can be included or omitted equally validly.
A question like "Is there a name for omitting all mentions of and in a list?" or "What do we call it when children breathlessly add and between everything when listing their day's activities?" would certainly be on-topic and answerable on ELU.
A question which is really "Does this use or omission of and suit my writing style?" would be off-topic on ELU and closed as opinion-based.
I'll leave Writers mods to comment about this site, its handling of topicality and migration mechanisms.
