I think we disagree somewhat. I believe buddy diving should be taught as sticking together within a diver-length or so of each other, reasonably vigilant and ready to assist. If two people want to dive "in the vicinity" of each other--maybe their goal is to be photographers--then I believe they should be taught that those dives are to be planned and executed as solo dives.
My issue with that is that it doesn't not reflect the reality of how many people dive. You've probably seen this scenario in Caribbean dive boat trips - the group plunges in, some people follow the group but aren't diving in close tandem with a single individual, and yet they're not carrying a redundant gas supply, etc...One or the other--solo diving or team diving--not a muddling of the two.
On the other hand, they are with a group, it's likely they could reach someone in an out-of-gas situation, and they're not having to plan and navigate the dive independently. It's not solo diving.
I suspect there are 2 'chicken-and-egg' competing visions for what models ought to be taught in courses. One is what you describe - a theoretical ideal of how some think dives ought to be conducted (e.g.: strict buddy or solo, no in-between), the other what I've got in mind...looking at what mainstream divers commonly do, and crafting a model around that - 'normalizing the normal.' What I'd like to see isn't getting rid of the 2 models you mention, but covering a 3rd.
I have in mind a thread or two from the past where fairly new divers got on dive boats and were perplexed others weren't doing what they'd been taught in class to be normal - such as BWRAF. When what people are taught and what they see conflict, it can cause problems.
