I think so too. It seems the change solely benefits llm users, and that support for llm integration would be more or less the responsibility of the maintainers from here on. If chatbots change or expand their api, auth mechanisms, add new features that can't go through this plugin interface etc, it would continue to divert core maintainer work on behalf of llm plugin maintainers, and increasingly tie the project development to llm development.
From what I've seen over the past few weeks/months, more llm users are agentizing and harnessing and looping and whatever and 'calling out' more, and it seems that interfacing with llms is only going to become more complex as the base models continue to provide diminishing returns and less stable outputs for their increasing power and time usage.
