Sure! Multiple discrete single page apps are simpler to develop and maintain, especially for apps that have a lot of dependence on the backend. IMO it promotes a healthy (aka obvious) separation of concerns and provides flexibility. A UI framework like Vue helps us cut a lot of corners when we need to, but no doubt, not every problem needs to be solved using the framework, the ability to retreat to vanilla when you can is hugely underrated IMO, especially given the _promising_ future of vanilla.
I completely agree, thanks to the webpack move it will now be a lot easier to take control over the chunking of the JavaScript. There are a few things in place already but it can be thinned out a lot more now.
