Yes, I don't think this matters. Much of "knowledge work" was always a proxy for something else.

High quality in terms of typos and errors is mainly a signal of respect in a similar way to wearing ironed white shirts with neck-ties. "Walls of text" that no one is expected to read in depth. Basically a symbolic demonstration of sacrifice and subservience (or something). LLMs remove this mode of signalling.

If quality of content wasn't examined before, it was probably never particularly important.
