I think it’s more telling to look at the opposite question, “what leverage would employees have to turn such a term down, assuming such practices were considered ‘industry standard’ and all employers of note made sure to include it?”
The answer in an environment with a ban on non-competes is “they’d either have legal recourse if someone tried to write them a contract with that term, or the term would be treated as non-enforceable and therefore harmless”.
In the current environment, broadly speaking, most employees wouldn’t have leverage to turn such a term down, and generally don’t.
