It is problematic because this inclusion would take place in the mere
act of visiting a file. That is more sensitive than things that get
included when you _compile_ the file.

That would make it safer, but you'd have to edit the file whenever
you change what you include.
I think it is better to achieve the desired safety by putting those
settings in the file itself, with something to say "search further back".
