The parsimonious folks who built my house back in the '80s carefully strung every wire run banjo string tight using an elven wire stretcher, and every fixture, switch, and outlet was installed with not one extra millimeter of length by a crew of agile, bony fingered gnomes with child-size hands.
That long-ago merry band of frugal imps also backstabbed every switch and outlet (time is money, you know), so 25-30 years later i also had to replace every single one of these after some of them tried to burn my house down and kill us and our cats. Such good fun trying to work with a complete lack of any sort of slack. Properly rewiring each outlet, especially the damaged ones where I had to cut back to unscorched wire, was like building a ship in a bottle.
So a bit of extra wire length is a good thing. Leave 'em alone.
By contrast, the thumbfingered orcs who did our plumbing used up every copper connector, elbow, and random length stick they had leftover from the rest of the neighborhood. It was all stuck together with pounds and pounds of bubbly solder and plenty of solder drips and scorch marks, as well as lots of greasy green fingerprints. Our house must have been the last on our block, and/or used for training apprentice plumbers. So that's been fun to repair over the years as well, and I've gotten very good at drywall patching and painting.
