The installation instructions seem to agree with you:

1. curl this shell script

2. Run it as root.

Anytime you see that, you can assume the software wants to take over the whole box and isn't likely to make any attempt to play nicely with other services/software/users already running on the same host.

To their credit, they do have a docker image (https://stalw.art/docs/install/platform/docker).

I feel like the developer is just as serious about containerized setup as letting it take over the whole box. I've run it both ways, and have found it works incredibly well in Docker and the documentation is very good at treating all setups equally.
