Today I learned that you can not only contribute to SteamDB via donations (monetary or in form of game activation keys) but also by using their Token Dumper tool to dump some information from your Steam account that can then get used to update the information on their site.
Since I regularly use their awesome Unofficial Steam Status page, e.g. just yesterday when there were significant problems with connecting to and/or browsing Steam, and occasionally use the main SteamDB site to find statistics or compare prices, I thought I might as well at least contribute something back.
Easy enough, the Token Dumper page automatically selects Linux 64bit as the OS type for the download, then extract and run ./SteamTokenDumper from the folder it extracted to. One can use the Steam Mobile authenticator to login via QR code by typing "qr" instead of a username when it asks you for it, then it scans your account for useful information. In my case with a funny little additional message
Requesting owned licenses from the store...
Store says you own 1129 licenses.
You own 3 licenses that the Steam client does not know about.
Whatever that may mean.
End result after submission is printed as:

│ After your submission has been verified, new information will be available on the site. │
│ You can run this again after you purchase or activate new games. │

which seems as it may at least provide some additional info for the database. So yay, I guess 🥳
They provide info on what the terms in the program output mean, and more, on an FAQ page for the Token Dumper
Apparently you get a "donator badge" on their site too if you submit "enough new information that we do not yet have". Let's see if my data was enough for that, but I suspect that's only for cases where you provide new app tokens 🤷
