I don’t hire developers who are tied to just one framework. I prefer someone who has a solid understanding of a platform but also a mindset to learn new technologies. You don’t need a large team, just one or two talented developers on a good pay package can be more than enough, and in my opinion, it’s worth it.
Hiring is hard enough and you want to add this additional complexity? Okay.
I would argue that hiring people expecting them to be fully proficient in all your stack is a much worse complexity to add
