Nothing whatsoever, except that event processing has to be considered
alongside conventional data processing issues and is not a panacea for
all problems.

Also, your IT manager might get very bored very quickly tasking a
Java/C# programmer to write / maintain every such query... :)

On the contrary: most CEP vendors are not concerned with "maintaining
hype" but about event processing solutions, and this temporal query is
a good example of a boundary in most CEP technologies. CEP is not the
same as temporal queries (although it can be used to help solve some
of those tricky event-based problems that include time-based aspects.)
