A couple of reasons:
* The "action" parameter (which is used to specify the <action> you want)
is already a logical indirection; the name of a bunch of business logic
that you want to execute ("save customer") without knowing anything
about the actual Action class that implements this logic. It would be
redundant to provide two different logical indirection schemes.
* Using a forward parameter instead of an action name would mean that the
page has no way to infer what form bean to use, so you'd essentially
have to give up all the fancy support provided for form beans.
