Can this pr fix this problem?
In vim9 call and let are not necessary, but everything behind silent and silent! are highlight as command, even function or g:thing, while exe and echo 's highlight are well.

Sorry @mao-yining, I missed your query.

Yes, it should fix that issue but that part is still on my machine. I'll update this PR soon.

Is this too restrictive? See my comment in #20191 (comment)

It is but it's a very old group that's no longer intended for use and scheduled for removal. I don't believe it matches anywhere valid but I need to test that.

\u\w\+ will match invalid patterns like :My_Invalid_Command. It needs to be [:alnum:].
It would be easier to read with very magic to reduce the \ overload.
POSIX character classes throughout would be better too.
Characters (like vertical tab and line-end) in [:space:], if used after a command, give errors. A tab or space only is allowed, so [:blank:] should replace [:space:]:

syn match vimUsrCmd	contained	'\v<[[:upper:]][[:alnum:]]+>%([[:blank:]!]|$)@=' nextgroup=vimBang

Illustrating with /\v<[[:upper:]][[:alnum:]]+>%([[:space:]!]|$)@= why it should be [:blank:]:
