For one BPEL does not express pi, so to do so would involve expanding the spec (whereas eliminating sequence reduces the spec). Second, for the purposes of business processes, where the notion of structured data is integral to the definition, it is only natural to not have to model XML data using a slew of pi processes: doing so would unnecessarily complicate the implementation of the BPEL engines and make direct reporting against process state impossible (while eliminating sequence marginally simplifies implementation, and has no impact on direct reporting capabilities). This philosophy amounts to "as simple as possible, keeping in mind the problem domain".
