Re updates: its all or nothing. Valhalla imports the whole Planet road network and its later chopped into the tiles. So, you cannot mix the different imports at all. So, to keep it all simple and visually OK, I opted for all-or-nothing design for all of the formats.
Verbosity: I think default setting was not that verbose
Desktop: these days you could go for PM and the server on the desktop as well. There are flatpaks available for it at flathub.
PS: was easy to look into it, since the reporting was very good!
