Apple has changed their mind a few times about whether Xcode and the CLT provide only the latest OS SDK or both the latest OS SDK and the previous OS SDK, but right now they appear to be providing both latest and previous.

When I ran Xcode once, Xcode itself offered to install Command Line Tools (or maybe it was during the installation process--not sure).  Anyway, I said yes again and still had command line tools.  And Xcode version 12.4 (12D4e) too.

Xcode does ask you about installing additional components when it is first opened, and if you do not allow it, Xcode quits, so you probably allowed it. But "additional components" and "command line tools" are unrelated things.

Yes, you are correct.  I remembered my interpretation of what it said, but not what it said ("additional components") until you reminded me!

I am looking at the About This Mac box and it says Version 11.1.  And for completeness:

% pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | grep version

version: 12.4.0.0.1.1610135815



So I guess there is still a bit of a mystery.  If I get some time I will try to build the new MacPorts from source and see if there is still a warning.  (I presently do not rely on MacPorts for mainline code and it is very easy for me to nuke it and do a quick reinstall.)
