Review snet implementation

[jdknives]

Describe the feature

While reviewing #724 it was discovered that a lot of modules depend on snet module for working, which may indicate the module implementation could be improved. We should review the implementation and check if we can decouple snet from other modules a bit more.

[jdknives]

This has two reasons:

1. snet was initially just a small wrapper and now seems to be required for most modules to start which decreases startup performance
2. it makes development more complex
