1 year ago I believe thats just the size of the package itself, but not including dependencies it then needs to install. I listed the total size of change to the heroku slug for each of the installs. If you look at the install logs on heroku itself you'll see the listing of X additional space needed for install when it goes through and installs each of the packages. I just forced a deploy to check it again and this is the output from xdg-utils, you'll see the total additional disk space at the end of the output:

Need to get 65.7 MB/76.0 MB of archives.
After this operation, 338 MB of additional disk space will be used.
In the readme, you have listed the installed size as 323 MB but I think it is actually 323 KB: https://packages.ubuntu.com/jammy/xdg-utils.
Maybe a typo?
