Ask HN: Are available domain names still important when naming a company?

From your experience, do you check domain name availability before naming a company? It looks to me like this is becoming less important...

There's many companies that either use alternative TLD's like; example.app or example.shop

Or prepend "get" or append "app" to the name to obtain the dot com TLD.

I also think that SEO and search engines make the actual domain names less important now right?
