IMO we should generically have OGL as the ONLY software mode, this is cross-compatible with Linux and Windows and every GPU supports OpenGL to some Extent, rather than keeping a DX9, DX11 and OpenGL software mode, just have one listed, this would be tidier for the code base with minimal drawbacks. As you say, there should be no special GPU requirements beyond drawing the result which pretty much every version of OpenGL can do.
I read on nvidia's blog that tesla drivers support will soon gonna be on legecy support , so. i think their will be No problem to go on and drop the support for older things which is already reaching thier limits .

I didn't think that Opengl (software mode) also will be dropped due to this, rendering a quad doesn't need any advanced features though.

SDL isn't much useful TBH.

While pretty much any OpenGL version _should_ work for SW rendering, GSdx currently insists on OpenGL 3, seems likely that soon to be OpenGL 4. This has been the main reason I ouldn't test PCSX2 on linux in a VM. It worked With SDL, but now everything runs fine except GSdx shows either a black window or doesn't load at all (do note that I didn't try it very recently though).
Also this subject is besides the topic, but still related to minimal requirements for PCSX2/GSdx (in SW mode).
