Gonna speculate here a bit since I'm not sure if this pattern exists in
Elisp land, but I've certainly seen (and written) programs that
required to be run from a specific place, usually from next to other
submodules in the same package. If you were to concatenate (or even
just move) such a file, it would break, possibly silently.
You can't even rename a program and be sure that it will have the same
behaviour, see busybox for an example of this. It's a single binary
that checks what name it's run under and then acts like that executable.
