Of course not.

Delphi is very well known for maintaining backward compatibility at
almost all costs.  Delphi 2009 was a significant exception.  But even
then, the decisions made regarding Unicode support were significantly
biased for backwards compatibility where possible.

My components don't state that they will support future versions.  If
someone installs one of my components in a version that I haven't
announced support for, then they are doing so at their own risk.  They
are liable for their own testing at that point.

I wouldn't put anything into production using a component library that
doesn't officially support the compiler I'm using.  I am sure that all
component libraries we use will have official Delphi XE versions well
before we put any Delphi XE project into production.  But,
unfortunately, none of them have support for Delphi XE today.  And my
team needs to begin our migration to Delphi XE now.

Of course not.

To put code into production that has not been thoroughly tested is
irresponsible, no matter what the scenario.  And I would agree that
stating that ICS will work well on all future versions of Delphi would
be irresponsible.  That wasn't at all what I was suggesting.  ICS
shouldn't announce or state support for a particular version until it
is appropriate to do so.

To reduce the amount of work required to support new versions of
Delphi is not irresponsible.  The VER based include files grow
significantly with each new version, since the _UP variables have to
be duplicated so much.  The approach I'm suggesting is much cleaner
and takes much less time to maintain when new versions of Delphi are
