Some gameplay and/or fluff reasons for why prerequites need not be corequisites:
-A society can go through earlier stages of development or models to reach a later stage or model, but doesn't always need to keep operating under the older model(s) after also starting to operating under the later stage or model.
-Older and newer policies don't necessarily make much sense to have adopted simultaneously. Policy C could require B to adopt, and B could require A to adopt, but C and A could be mutually exclusive.
-There are limited slots, so being able to de-adopt a policy after reaching something it unlocks gives options for taking other policies instead.
-If the later policies have some substantial costs to maintaining them, then de-adopting the prerequisite is risky, since if one then has to de-adopt the later policy due to those costs becoming too burdensome for the empire, one might have an even longer series of intermediate prerequisites to get back to the later policy again than if those intermediate prereqs had been maintained.

It's an option, but they are also available from Interstellar Infrastructure. Could probably also add them as unlocks for having some particular bureaucratic species in the empire.
