The difference between SOAP and ZO+ is the level of integration and
dependency. If you do a change in the ZE there is a very high chance that
you will not have to touch any code in SOAP, but you will quite likely need
to adjust something in ZO+. Phar is the only of the current extensions that
comes anywhere close to this. And ZO+ is still a *lot* more tightly
integrated than Phar (and you know what a PITA Phar can be...)

If you don't see that ZO+ is an extension that is very tightly integrated
with the ZE and rather sensitive to change, then sorry, can't help you. To
me this seems obvious.
