ICD registration of Altera OpenCL platform

For question# 1 I can't comment on future features/release dates but trust me, this request is taken very seriously. The less vague answer would be to talk to your FAE, they may be able to give you a more concrete answer than that.

For question# 2 one method (haven't tried this but it should work) would be to compile an AMD/Intel and Altera code base into seperate static libraries then link them both into the main application that will use both. You still won't be able list out all the platforms but at least you will be able to have both implementations linked into a single host application that way. I know this workaround is not pretty but if you do go down that road I recommend making a really simple test case first just to make sure this actually works since I haven't tried this personally.
