Your example of 'split -a' is required by POSIX, so it should work on any
Unix system, even when GNU coreutils are not installed:

but other options, like 'split -C', are GNU extensions.

Long options are also a GNU extension.  By the very definition of
extension, you cannot expect other Unix platforms to provide the same set
of extensions as GNU coreutils, although you should be able to install GNU
coreutils on pretty much any of today's common Unix systems to get your
favorite GNU extensions.
