This has been implemented. Tech Note #129 describes the SysEnvirons trap,
which will give programs information about the system. The mechanism uses
version numbers on the information records, so it is extensible. The
first version does not include information about Multifinder (since it
hadn't been released at the time), but I would expect that future
SysEnvirons version will include that information.
MacApp 1.1 has its own capabilities record, which is automatically filled in
when the application starts up.
