Using app.set vs app.value in Express

Question

In my app.js file, I use app.set(valName, value)to pass several configuration parameters to my routes.
Then I pass the application on their routes: app.use('/', require('./routes/index')(app));
Then I can easily use app.get(valName)to extract values ​​in routes.

My question is: would it not be easier to just use app.valName = value;and then just access the app.valNameroute?
Do I need to use .setand .get? Or will it break something?
