I think this is fair - it would be ridiculous to expect disclosure of the use of a dictionary. I'd be in favour of this being down to social norms / personal behaviour because I think it's not the most clear thing in the world. 

I still personally think there's something qualitatively different. Imagine you have to go through 80 pages of calculations and the author tells you they used a calculator which routinely makes errors at random. In theory you expect the author to back their work and have checked it... in practice.... I worry lots of people don't.. As a consumer I'd rather know what tool was used. 

Another analogy would be how code and packages use are standard disclosures in papers. 

Hey Emmanuel, 

This is great! I am the incoming director of research for Ambitious Impact - I'll try to reach out via email over the next few weeks with some thoughts on how we can trade notes.
