Two sides give something and meet in the middle. That is the promise inside the word, and it is the reason the word keeps getting used for arrangements where only one side gives.
A letter goes out banning bonnets, du-rags, and bedroom shoes from class, and calls it preparation. The exemptions turn out broader than the coverage suggested; the argument underneath is older than the letter. It is the one Booker T. Washington opened from a stage in 1895, where the terms of the meeting were set by the people who were not required to move.
Ask of any compromise what each side put down. When the answer comes back lopsided, the word is not describing the arrangement. It is dressing it.
