sadly, this would discourage me, and
probably anyone else involved in a
production setting, from using the
new track if it is set up unalterably
this way.  it's often possible to make
temporary adjustments and proceed through
an entire file, accumulating all errors
and warnings to be handled in a single
manual pass.  not always, but often enough
that it's worth the effort to make an
on-the-spot decision whether to cancel
or proceed.
