Obviously they are not used by current RDB VMS applications.

Question is whether the companies currently running RDB VMS
would be interested in such features.

And whether companies currently running XYZ ABC would
consider VMS if such features would be available on
VMS.

Probably not many but maybe some.

I believe that companies actually manage to run high stability
and availabilty databases on other platforms.

And embedded SQL is not the current trend in database access
technology.
