Hard agree.
Less code is not a positive metric to measure your implementation by, and is not a valid premise to justify itself. Often increasing the complexity (again, LOC is not an indicator of complexity), tanking performance, and harming the debugging experience is a common result of the mentality. Things that make software worse.
Not all one-liners are bad ofc, that's not the argument I'm making. It's about the mentality that less code is more good, where poor decisions are made on a flawed premise.
How difficult would you expect it to be to go back and produce ADRs for significant decisions in the past that resulted in the current architecture and structure of a small-medium sized project?
