Putting external actors/object within the map folder itself

I always have problem with this new one file per actors. so when i debug it is very often to remove and recreate a map with the same name and usually I forget to take care of external files and this cause to have issues you can guess .so why so serious?
why don’t just put the external actors/object within the map folder itself?
this way we don’t need to be so sensitive about map names and easier to delete and recreate for developer. lower probably of bug. I don’t really see the reason behind putting them in some where else.
