Like Parth2187 correctly said, Odin is mostly used to flash recoveries, modems and firmware files.
All ROMs available in development section are zip packed, so no they can't be flashed through Odin.
For a ROM to be flashable through Odin but you would have to pack the /system folders into img file followed by .tar compressed extension. And finally a md5 sum would have to be generated for it to be valid to flash through Odin. This would take a bit of time for each updated ROM file, so the developers prefer to release recovery flashable zips instead.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
