I'm fine with that, but keeping some consideration to optimization should still be something, even in environments when constraints are low. The problem is when no-one cares and includes 4 versions of jquery in their app so that they don't have to do const $=document.getElementById, everything grows to weigh 1Gb, use 1Gb of ram and 10% of your CPU, and your system is as sluggish nowadays (or even more) than it was 10y ago, with 10x the ram and processing power.
