I’ve already felt like I should choose shorter names in a (shitty) project where the customer asked us to use an auto-formatter and a max line-width of 120 characters.

Because ultimately, I choose expressive variable names for readability. But an auto-formatter gladly fucks up your readability, breaking your line at some random ass point, unless your line does not need to be broken up.

And so you start negotiating whether you really need certain information in a variable name for the price of badly broken lines.
