Unmatched events are a problem in MIDI. MIDI processors and sequencers working with files may to some degree try to repair such problems, partly because they need to do so when cutting and pasting regions as well. But you don't get guarantees.
Thanks for explaining this. I guess it would also be an option to emit end events at \fine but not start events, if they can be told apart. A third option: get out of this uncomfortable situation by changing the syntax (it hasn't made it to a stable release after all) so that which events are included and which are not is fully explicit in the ly code.
