I tried that, both with custom classes and cfengine-defined classes but it
doesn't work.

Tried both of those as well. Maybe it's a bug? (if it's supposed to work)
I do need to undefine/negate a cfengine-set class (have_aptitude, set in
sysinfo.c). I have:
$ cat test-cls-override.cf
body common control {
bundlesequence => { "report" };
}
bundle common g {
classes:
"have_aptitude" not => "any";
"foo" expression => "any";
}
bundle agent report {
classes:
"foo" not => "any";
reports:
have_aptitude::
"have aptitude";
!have_aptitude::
"do not have aptitude";
foo::
"have foo";
!foo::
"do not have foo";
}
$ sudo cf-agent -f ./test-cls-override.cf -I
R: have aptitude
R: have foo
