In many larger enterprises, they actually deploy systems with their own
CA installed into the system global certificate store (possibly removing
certain other CAs from that set too, and distributing their own version
of the relevant package that maintains the CA set).

I agree with Magnus that most other SSL apps do default to the system
global cert store and it's generally what's expected.
