Since posting this information to twitter and sysprogs forums, I've learned some interesting (and cool) things:
1) The clever folks at Sysprogs have their own "zadig-like" USB driver tool (strategically called USBDriverTool), that unlike zadig, has a " put back the original drivers " feature:
And can be downloaded (free!) here:

2) Additionally - the kind support folks at Segger responded to my email and pointed out that VisualGDB also supports talking to the Segger GDB server directly (instead of using OpenOCD). There's even an excellent example:
https://visualgdb.com/tutorials/arm/stm32/
Note in particular that instead of picking the J-Link device from the OpenOCD Debug method drop-down list, that there's a "J-Link JTAG" debug method also listed!
3) The Segger folks also have an explanation on the J-Link showing up as a BULK device in Windows. This is not a problem I had, but I am including this as relevant:
https://wiki.segger.com/J-Link_shown_as_generic_BULK_device_in_Windows
The screen snips there appear to be from an earlier version of Windows. Additionally, as noted in my proir post - simply selecting "Update Driver" would result in Windows saying that the drivers are already the current ones (even though it does not work). So you may need to delete the drivers before attempting the update when seeing this "BULK" driver issue.
