I don't think _you_ (nor I in my personal capacity) would, but your provider definitely should, and then you get the benefit.

So if you're hosting via some accelerator like Cloudflare, AWS API Gateway, whatever Google has in this space, or app host like Heroku and friends, they'll happily do the work because they get the aggregate benefit. Your own site will become marginally faster or have happier roaming users, and so on, essentially for free.

When you're developing a generic website, I don't think you should care about this. When you're self-hosting, you can decide if it might be worth it or not. It probably won't be worth the effort unless you're doing something really intricate or special, in which case you'll be really happy that you have the option.
