I also think evalbytes and fc and say are special cases.

fc is corresponding to lc, uc
say is corresponding to print
evalbytes is corresponding to eval

These are already core keywords.

On the other hand, trim is a mere function.

I feel that it is easier to get consensus by adding functions to the module.

  use SomeModule 'trim';
