see #8382 for context - if two packages install the same file it would be useful to know this.
I'm in two minds about this warning, I expect both true and false positives are rather rare and it's hard to evaluate which matters more
this warning would surely have given a clue in 0-byte files getting unpacked #8382: knowing about it when it really is unwanted seems very desirable
adding this warning will likely expose this repository to a small trickle of issue reports, of varying legitimacy
