Some ST drivers can be ported easily to Hubitat, others are not so easy I’m sure. Not being a developer myself, I don’t know much about what makes it easier vs. harder to port, but this thread would be the best starting point:

App and driver porting to Hubitat

I’m curious, did they do an official integration with Smartthings? Or did they create a custom app/device handler and make it available to users?
