It also says on the map features page:

You can use any tags you like as long as the values are verifiable.
However, there is a benefit in agreeing to a recommended set of
features and corresponding tags in order to create, interpret and
display a common basemap.

source=survey is one such tag in the recommended set of features,
source=GPS isn't documented on the map features page nor on the
Key:source page.

Then use:

source=survey
survey=gps
gps=model/device.

Simply stating GPS is no better than stating survey because you don't
know what type of GPS was used.

Doesn't mean things shouldn't be made consistent where possible.
