The volume is completely contained within the docker ecosystem so if anything happens to the docker install, we’ve lost the data. OK, OK, I know it’s in C:\ProgramData\docker\volumes\ on the host but still I’d prefer to have more control over its location.

It’s worth reading the whole thing, even though this isn’t the best way to keep data long-term.  It’s important to know about this strategy even if only to keep it from accidentally ruining your day later.
