Many web applications use persistent database connections for performance
reasons.
I suppose it's unlikely for webapps to update a row and then sit and wait a
long time for a hit, so it shouldn't affect most of them.
However if long running transactions are to be aborted automatically, it
could possibly cause problems with some apps out there.
Worse if long running transactions are _disconnected_ (not just aborted).
