t’s not sad, just the way things are, modern compilers are doing much of the checking older tools like lint used to do.. OpenBSD and DragonflyBSD both killed lint ages ago.
OTOH, we should probably consider other tools, like sparse:
https://sparse.wiki.kernel.org/index.php/Main_Page
The license is fine and it plays nice with the compiler.

Where is this policy written? If we have to, my guess is we can announce the deprecation in 11.2. A policy that would force us to ship xlint in 12.0 would just be a bad policy.
"xlint" is/was an internal development tool not a utility of any usefulness for non-developers. I would compare it to the disappearance of the C Preprocessor when we moved to clang, with the significant difference that the lack of C a preprocessor broke some ports.

If someone needs it the/she may submit it in the ports tree, like we did with other stuff that has been deprecated.

So … can we remove ctm(1) ?
