That's a different issue.  The original question was about the splash screen and specifically about emacs-version.  I see no reason whatsoever to show information about the native compilation there, as it's a minor feature that moreover has no effect at all until some Lisp files are compiled with it.  Besides, the splash screen is already too crowded.

If you are saying that the "About Emacs" display should be redesigned (to make it look differently from the splash screen), I might agree, but then (a) please show a more detailed proposal, and (b) such a display doesn't need the change to be in emacs-version, it can use the other variables which divulge the details of the build and its configuration.

Btw, in line with the recent "let's be like other apps" trend, I suggest to look at what other apps do in their "About" display: I have the impression that this fashion is on its way out.

Bottom line: you've effectively changed the subject, so I suggest to do that explicitly, and start a new thread/issue.
