In Fedora 21 we show any valid application in the software center with an application icon of 32x32 or larger. Currently a 32x32 icon has to be padded with 16 pixels of whitespace on all 4 edges, and *also* has to be scaled x2 to match other UI elements on HiDPI screens. This looks fuzzy, out of alignment and lowers the quality of an otherwise beautiful installing experience.
For Fedora 22 we are planning to increase the minimum icon size to 48x48, with recommended installed sizes of 24x24, 48x48, 64x64, 256x256 (or SVG). Modern desktop applications typically ship multiple sizes of icons in known locations, and it's very much the minority of packages in Fedora that only ship such small icons.

This icon really deserves more love by upstream.
Thanks for reminder Jaroslav
