The change completely removes support for lowercase file extensions (.r, .rhistory, .rprofile). While .R should be the default/preferred extension (first in the list), the lowercase variants should still be supported for backward compatibility. Many existing R files use lowercase extensions and would lose language support with this change. The extensions array should include both uppercase and lowercase versions, with .R listed first to make it the default.
