In the past when I've seen someone extolling Windows/Linux compatibility for something as complex as a detailed Emacs setup, they were using WSL or one of the wrappers like Cygwin rather than native Windows compiles of the tooling.
(I admit it's added up to more than zero though! Keeping (require 'cmake-mode) working reliably on Windows and macOS has proven a minor annoyance, and fonts seem to require a degree of system-specific attention.)
