I see where you're coming from, but as someone who regularly interviews engineers, I don't care about specific tech stacks when evaluating a candidate very much either. I can only think of two positions I've worked in where such a thing really mattered.

A good engineer can adapt and catch up without a lot of lead time. For a contractor, I'd be much more specific - but for someone who's going to join my team? I'm looking for a candidate that can demonstrate their problem solving ability, creative thinking and communication skills.

Other than having some kind of experience in the general domain we work in, those "soft skills" are far harder to find than specific tech experience.
