This seems to be more complicated than Nicolas's version, and involve 
much more special magic, like the name __nsmeta, and the class that does 
nothing. I'm also not clear on how you're picturing the relationship 
between namespaces and packages.

The way I understood the suggestion, you'd end up with something more 
like this, which feels much simpler and cleaner:

#
# File: /lib/company/project1/a/b/MyClass.php
#

<?php

declare(package=company/project1);
// or with a new keyword
package company/project1;

namespace company/project1/a/b;

...


#
# File: /lib/company/project1.php
#

<?php

namespace company;

class project1 extends \PHP\Package {
     public function getParserDirectives() {
         return [
             'strict_types' => 1,
             'strict_operators' => 1,
             'upgrade_errors_to_exceptions' => E_ALL
         ];
      }
}
