Are we abandoning the possibility of a second postdoc - Biochemistry/Life Sciences?

I’ve been joining career events for postdoc recruitment, almost all of them don’t even mention the possibility of this being a second postdoc to people in the audience.

Doing a postdoc that requires you to be in person (3-5 years, similar to doing a PhD) requires individuals to not have any obligations pop up or family emergencies…. And if you’re already in a postdoc for 2-3 years, it becomes impossible to find another postdoc at great institutes because many of them are installing a 5 year cumulative cap.

What are people supposed to do? - postdocs are employment opportunities for PhDs at the end of the day, and culling the group of applicants to prefer fresh-PhDs is detrimental to the total group of PhD-havers especially in this job market.
