Quite a few languages do if expressions, and IMO they’re great. Simple syntax, readable and powerful. It’s crazy to me that any new language wouldn’t have them.

The argument specified in the docs is "a language needs only one conditional flow construct" (in a language, of course, that has half a dozen conditional flow constructs ...)

  Ken Thompson has been writing compilers for over 50 years now. If you believe that Ken "barely knew how to get a compiler working in the first place", we have nothing to talk about, as you obviously made up your mind already.

    Then read the source for the compiler yourself. Tell me I'm wrong.

      Not only I have read it, I have written several compiler targets for it. You are wrong. It's by far the easiest compiler I have worked with.
