Where/how is this file used?
Also wondering about the removal diff (e.g. "dcf").

Where/how is this file used?

This is what it is used when you run devtools::spell_check().

Also wondering about the removal diff (e.g. "dcf").

This is automated. It is removed, presumably because this term no longer appears anywhere in the docs, and thus no longer needs to be listed as a known spelling "error".

@AshesITR If I may self-promote, I talk about a number of such automated checks in these slides.
