What about the huge majority of BITNET sites which don't have a shared
file system because it performs so poorly on large systems that IBM
refused to release it?

Maybe, in 5 years or so, when and if SFS is available for all types of
machines and everybody has migrated to a version of VM that supports it.
For now, I'm afraid you'll have to forget it.

Why would it be easier to maintain? You still need a FILELIST file to
define who is authorized to do what to the file.

The files would still have to be stored under a different name, for
security reasons (or rather, the mechanism for storing them under a
different name would still have to exist for security reasons, so the
overhead would still be there, even though the default mapping might
become "same fileid"). Besides which, this particular overhead is
negligible compared to the time it takes to find out in what filelist "A
B" is defined when the user doesn't specify "C" and there are a lot of
files available from the server.
