I agree, and I don't argue with the desire to have a set of separate
routines which suits someones goals better.
But the exception handling is a real problem, because it affects ALL units,
regardless of whether it uses your 'better API' or not:
as said it renders the code inoperable with all other code.
Hence my proposal to refactor it in sysutils, so at least the exception handling
can be kept common to all units.
