I think you were right where I was with 16.3 ... with my above post.. I upgraded to .17 and didn't do anything to put Caddy in place... so traefik was still working... probably could leave it like this.. but how long till it breaks would be unknown... Sooooooo ... What I then did was edit my composer file using the new default composer as a reference to copy paste the caddy config into my composer file (you can see this above .. its just that + 2 volumes at the bottom of file not pictured) ... this worked no issues.. and I can probably now cleanup my commented out section.
