And most of my friends and colleagues would take a full remote role that pays half what big tech, 5 days in office pays. Add in an extra week of PTO and you have a great pitch to devs.

I'll believe it when I see it reflected in applicant resumes. (east coast tech firm)

What do you mean? You’re not getting applicant resumes to your smaller org?

I personally turned down an Apple offer because they required 3 days in office and went this a much smaller fully remote team.

You can incentivize people to stay with things other than salary. Salary plays a part of course, but there is a lot of other aspects that make staying at a job worthwhile.
