I am not convinced that
portability is a must have either, but that is a choice developers should
make. What I am not totally comfortable with is any new spec. addition that
would basically imply that using the addition would break portability.

In a sense. Although I have heard of
teams developing on free-dev license servers then deploying on high-end
servers. Also, app. servers tend to be changed far more often than
databases, thats the feeling I get talking to developers
anyway.

I
agree that portability is important to a component vendor.
But
how important is it to those who are developing business applications that won't
be re-sold? I think in many cases, portability is a "nice-to-have", rather than
a "must-have". The must-haves are the features and capabilities that provide
direct business value. If you are not a component vendor, portability doesn't
typically provide direct business value. It is, of course, desirable to isolate
the non-portable areas of the application design/implementation as much as
possible.

Don't
get me wrong ... I'm all for portability. I'm just not convinced it is typically
a "must-have".

If you rely on the algorithm provided by your app. server, then it is possible that the same algorithm may not be available on other app. servers. This is definitly not something that a component vendor (if there are any out there) would want to do.<stuff omitted ...>
