I too think that has some weight to it, but there's no reason we can't have both.

Before the LLM boom, I wouldn't have thought twice about having fine-grained options, but since then, every SaaS company on the face of the planet has forcibly bundled ChatGPT and its ilk and jacked up prices — LLM crap I don't use and don't plan to use in its current state.

Similarly, many might wanna go initially with a simple option but later, based on their usage, whittle it down to the few that are relevant, save money in the process, and commit to the company.
