Is this warning anything I should be concerned about?

It can be ignored. Those libraries aren’t used on non-Windows platforms anyway. The warning has been fixed in the Canary channel and will make it into the next beta version.

If it’s bothersome enough to call for that, it might be worth trying to workaround by giving it the .dll

Your choice, but the actual fix was to NOT delete the file, so replacing the file has the same effect.  
[Do not remove Alpha VSS dependencies in installer packages #4178](https://github.com/duplicati/duplicati/pull/4178)  
or you can run Canary (which is always an unknown), or wait for the Beta, or workaround in script.
