Re: "Scope" of licenses to be covered by SPDX
I sometimes skirt the issue by broadly referring "software that is freely available on the web."
When one is talking about new projects, picking licenses, and the like, it makes sense to steer/limit to OSI approved licenses. When, on the other hand, the use case is documenting all the "junk" that may be found in a package and associated licenses (as with SPDX), it makes sense to be expansive in order to be able to represent software under licenses outside the OSI definition.
So, the SPDX license list goes beyond the OSI list. Our goal has been to handle the bulk of license one might run into in a software package. And, the spec provides a mechanism for handling licenses not on the list, by essentially including the text of the license. One of the benefits of the License List is that it keeps the size of the SPDX file down by not requiring the text to be included.
I don’t think we've come to grips with where we draw the line on the size of the license list. With the 150 or so license on there now, we certainly handle the vast majority of components, but for user convenience, more is better. I think when we get comfortable with our understanding of the effort involved in maintaining the list and adding new licenses, we'll be in a better position to say how big we want the list to be.

The Free Software Foundation (FSF) and the Open Source Initiative (OSI) are the two organizations which, in my opinion, define what FOSS is. Any attempt to define FOSS which do not take into account the collective wisdom and process that went into their respective license lists  would be a big mistake.
FOSS = Free and Open Source Software, which is the union of software which meets the definition of Free Software and Open Source Software.
I have seen attempts in the past to expand the definition of FOSS beyond licensing to include other parameters such as open development processes and the like. They've all been spectacularly unsuccessful. There be dragons.
In the interest of full disclosure, in addition to by day job at the Eclipse Foundation, I am also a Director of the OSI.
