how does that work if you wont be hired without prior experience in a particular stack to begin with
for current employment I’ve only ever seen teams push for using the next shiny thing solely to get that experience and professional validation in the current role, to be competitive for consideration in the next roles
It's unfortunately accurate that a lot of roles and people in those roles are indeed purely bullet-point driven for their resumes. If you're entering a role at a mid-level or junior, you're likely stuck with their tech stack choices. At senior or higher, it's usually about delivering results and the tech stack is up to you.
I've never paid much attention to specific job requirements, just whether or not I could solve the problems they were looking to solve.
