For a recent post (Solve IO::Pty warning issues from Net::OpenSSH) I tried to create a new category for warnings for a module and then disable it but it failed (perl 5.34.0) when I used it as *I expected*:

{
package XXX;
use strict;
# register a new warnings category with this package name
use warnings::register;
sub expected {
        warn "ajajaj";
}
sub correct {
  if( warnings::enabled() ){
      warn "ajajaj";
  } else { print "not warning!\n" }
}
1;
}

# it's already loaded...
#use XXX;
no warnings('XXX');

# this says 'no' (as expected)
print "enabled: ".(warnings::enabled('XXX')?"yes":"no")."\n";

XXX::expected(); # this still warns

XXX::correct(); # this does not warn

Firstly, correct me if I am doing something wrong.

Secondly, am I expecting too much to just register a category within a module and then anyone from outside it, to enable or disable it? Why the check to warnings::enabled() in each and every warn() statement of that module. That makes refactoring to using warning categories very difficult.
