I only actually knew about the "source code" file type, so thanks a lot for this info. I loved that the license information actually gives a brief description for each license and helps out choosing them, and I think that is basically my point, I only found out about this stuff after posting in the forums about it.
What I wish is that it was more incentivized in some way, even just sharing the source code as a file is a weird choice, when most likely the source code is already being hosted somewhere and could be easier to update. I see how it being already used by some people (and hopefully I'll start doing it myself now) but I think it should be more explicit to users, I can't even agree it's a streamlined process now, it's a bunch of different hidden processes.
