Precisely - and I am actually not aware of any tools (apart from
Microsoft Excel and OpenOffice.org Calc, of course) that handles the
leap-year bug "nicely". Even Microsoft's own .Net library pukes when it
encounters a value of "1900-02-29".

Insisting that the leap-year-bug should be allowed in documents for
conformance class Strict is in my view an attempt to "legacy-enable"
Strict - and I strongly oppose that. The rationale/idea behind S was not
to be able to make it as easy as possible for implementers to transform
documents from T to S. The idea was to get rid of the legacy heritage of
the binary document formats - yes the namespace-change itself was an
indeed attempt to make the distinction between S and T as clear as
possible - not least from an implementation point of view.

Trying to justify features in S based on the practicality of moving
documents from T to S is in my point a misunderstanding of why S was
created in the first place.
