Part of it has to do with strict testing in CRAN as well. Packages have to pass tests and confirmed to compile. This adds reliability to package management across platforms. That said I still run into trouble with package deprecations. I was trying to install the optmatch package (deprecated but still used by causal inference packages) and had a really tough time getting it to compile on macOS.
