Thanks for the explanation! Still, you haven't replied about what other mice
emit for scroll events.

>> No, I never changed any settings. Are you saying that the software changes
>> some settings inside the mouse itself, as opposed to OS/driver configuration?

> yep, on many devices this is the case. google e.g. libratbag or solaar as projects to do exactly that.

For R.A.T., I found ratctl (https://github.com/MayeulC/Saitek), which claims to
have completely reverse-engineered the USB protocol. Here's what the author
says about it
(https://github.com/MayeulC/Saitek/issues/4#issuecomment-283506849):

>> I'm not talking about tweaking the computer settings... is there a way to re-program the mouse itself, or what does the Windows/macOS configuration software that ships with the mouse do?

> Not as far as I know. I am reasonably certain that these utilities either change the driver behavior, or generate virtual events that are directly interpreted by the windowing system.

So it should be safe to either add hwdb entry (if this mouse is rather unique)
or change it for all mice, if they all emit events this way.

By the way, if this button-mapping configuration is a client-side thing, it
would be cool if GNOME offered a settings panel for it, like it does for Wacom
tablet/styluses. I realize that this is a wrong place to ask for that -- but
what changes to libinput would it take to make that possible?
