[rules-users] wrapping drools api?

[thomaskukofka at web.de]

Hello,

some people write about wrapping the Drools API with an own access API 
for integration in the application.
Sorry for the perhaps stupid question, but what is the reason for this? 
Does this only make sense if  I'm thinking about changing the rule 
engine one day?
If I'm not intending to change the rule engine from Drools to another, 
so isn't it the same if the developpers has to use the native Drools API 
or an self-written access API?

Regards
Tom
