Out of curiosity I did a bit of a search and you're certainly not alone. There was even a YouTube video from a housing association where Comcast had done something like 50 drops barely buried. They fought back via social media and a local TV station and got results, but a hassle. On the video they brought up the tripping hazard and its potential legal consequences.
I'm wondering if you had installed buried coax yourself to the service point, if they would have refused to connect to it, insisting they have to run it.
