Newsletter signup form uses LiveView https://veloplanner.com/newsletter/new
I was testing LiveView with page transitions and it was working quite nicely with maps as well (maps were handled by JS of course). You can play with it here https://travelermap.net/ - you can check search (cmd + k) which is powered by LV.
EDIT: As for plans for veloplanner, I'll be adding some of the interactive features (comments etc) as LiveView.
