Why would you use LF if the focus of the application that you develop is Windows? You make the life harder for these users. :-)
Seriously: your argument typically comes from developers who consider GNU/Linux as a first-class citizen as a development or deployment platform, and Windows only as a second-class citizen (assuming that a Windows port actually exists).
I can accept an argument like "I, as a developer, don't care about Windows and its users, so all my source code is in UNIX format." This is a conscious, though quite political decision.
But an argument like "not using LF makes lifes harder" without a relativization on which premises this claim is build (such as "GNU/Linux and macOS users are much more important for as, and if there exist any users or developers who use Windows, we consider them to be undesired, because they make everybody's lifes harder") is intellectual ignorance.
