It’s all about perspective. In two companies now, I’ve been in teams that don’t really care about my tech stack. It was mutual, of course. You can blame the company for making these teams up (I did/do), but that how things are.
It is very weird to be in a situation where (for example) we’re working on a project in python and one person refuses to use python. Weird enough that I’ve never seen anyone with a personal tech stack, most people just try to adopt the local custom of the team they’re hired into.
Why should I care about the teams’ other tech stacks (and vice versa)?
Relatable. I'd love to talk to them about my private Rust projects.

But... how did this work out in practice? There's a software project in language X, framework Y, domain Z, which everyone was familiar with, and you were brought in not knowing X and Y? That's like hiring for a Java position where the applicant couldn't care less for that the language. Strange.
Current job, I was hired in a team of macOS devs for a macOS product. Several reorgs, mergers and downsizing, my old team is basically gone, and I find myself in a team of web devs and backend engineers.
I do miss having people around who can keep up a conversation in my tech niche.
