Yes, in an ideal world, that'd be great for both humans and LLMs, but we are about as far from that ideal world as we could be. You can't even do some of the "advanced actions" as a human with human-level reflexes without encountering a captcha, but sure, all of a sudden, everyone will just decide to make their bread and butter that is data easier to explore via an LLM.
Why on earth would they offer convenient hooks for AI chatbots?
Watch how fast Meta adds this if a new hot shot social media app succeeds by designing for AI agents controlled by users.
This is the exact opposite of what will happen (and in fact what has happened). Reddit is suing Perplexity right now for scraping.
Meta will not serve content to some other app for free - for what benefit? They will not see advertising data.
Advertising isn't the only possible business model.
And profit isn't the only possible motive to provide a service.
A closer analogue would be AppleScript, or rather, the underlying Apple Event and Open Scripting Architecture functionality supplied by the OS to support AppleScript, that allowed applications to expose these interfaces along with metadata documenting them, and for external tools to record manually performed tasks across applications as programs expressed in terms of these interfaces to make them easier to use (this last bit, while not strictly required, is convenient, and especially useful for less technical users).
If you're familiar with VBA in Microsoft Office applications, sort of like that, except with support provided by OS APIs that could be used by any application that chose to implement scripting support, official guidance from Apple suggesting that all well-designed applications should be scriptable and recordable, and application design patterns and frameworks designed with scriptability and recordability in mind.
Note that I use the past tense here, despite AppleScript still being available in macOS, because it is not well-supported by modern applications.
There are no shortcuts in life and its just expensive text autocomplete.
"Lets spin up $750k in GPUs full throttle to scrape a web page with my $200.00 CC subscription."
Everyone is delusional.
