[ Question ] About Master Seed insertion in Python Code File.

I recently exploring zeronet code to port to another language, but i found code in
func src/main.py>Actions.main()

https://github.com/HelloZeroNet/ZeroNet/blob/454c0b2e7e000fda7000cba49027541fbf327b96/src/main.py#L138
```
# Default action: Start serving UiServer and FileServer
def main(self):
from User import User
user = User(master_seed='MY_MASTER_SEED_HERE')
print(user)

...
```

is this file modified to include master seed, is there any specific reason to do so ?
