For example, if your company has a splunk install for log surveillance, it has a default of M/D/Y year format for all date ranges etc, it's a bit confusing, but it has localization too of course.
Developers who do devops tasks might run into this one.
Developers? Maybe but even if we accept that all developers pay close attention to their date formats to avoid misinterpretation errors, others who produce work within the developers workflow are certainly not doing so.
Developers and their APIs might not be. The user-facing software often does, and it often does not let you switch, at least not without affecting other things (such as the spelling of “colour”).
