There's a lot of things that don't fit on GitHub either. Sometimes because it's closed source, sometimes because the data is too big, sometimes because parts of the data have legal restrictions on distribution and require the user to get it themselves from a different source.

The usual solution is to make a skeleton repo with only partial or no code, the real substance being a README that explains what the project is and instructions on how to use it. GitHub is a social network as well as a code warehouse in a way, and this comes with benefits. The same system for stars, issues, user groups, permissions etc. extends across all projects regardless of whether the code/data is actually hosted on GitHub. Something like this for science could be of huge benefit.
