Laravel uses Macroable class on the guards, why not here too?

Shouldn't it maintain consistency?

Thanks for your feature suggestion, @jose123v! I think that makes sense, and I see no issue with adding support for that. If there are any volunteers, this would be a great first issue for someone to take!
