I am not so sure. I think what’s running might not be “Qualcomm Location” but instead " XTRA – Predicted GNSS Satellite Orbit Data" as written about here: Privacy Policy | Qualcomm
The relevant section might then instead be:
XTRA uploads the following data types: a randomly generated unique ID, the chipset name and serial number, XTRA software version, the mobile country code and network code (allowing identification of country and wireless operator), the type of operating system and version, device make and model, the time since the last boot of the application processor and modem, and a list of our software on the device
This looks approximately consistent with what you were seeing in the user-agent string, right?
It’s still some information disclosure to upload that information (and not even over HTTPS, so any MITM can read as well!), but not at all as bad as GPS locations and Wifi towers.
