On the subject of super calls, the report actually says "Support for these
features may be *reduced* in later product releases." It doesn't explicitly
say they will be completely eliminated. It might just mean that their use
may be subject to further restrictions.
I have a practical reason, not just one of taste, to vote for the retention
of super calls in the language. As well as developing with BlackBox, I write
software targeted to Microsoft's .NET Framework using QUT's Gardens Point
Component Pascal compiler.

Currently the use of super calls is unavoidable in order to comply with some
of the requirements of the .NET framework.
