Running soffice in server mode for multiple connections

[_savage]

I've read several posts about using soffice in server mode, some using named pipes to connect and others using ports. I'm sticking with pipes because all runs local on the same machine. However, I noticed that most posts are outdated, and at least a couple of years old.

So my question is: what's the current status of soffice and using it in server mode? How well does it scale these days; will I still have to use workarounds like oodeamon or jodconverter?

I also read of the -env:UserInstallation command line option (e.g. here or here) which allows me to spawn multiple soffice instances, each of which with its own named pipe. That would also allow me to "scale" to multiple connections. Poor solution?
