#os is there as part of the original refactoring to support delegation in favour of a giant monolithic SmalltalkImage.
#platform was added later as a better(?) delegator for some of the methods, and is Pharo-specific.

All methods in SmalltalkImage that do the same as OSPlatform should already be deprecated, and expected to be removed in future releases. 
Having them there helps people port their code, though I'd personally prefer the messages to mention Smalltalk os rather than OSPlatform.
OSPlatform does not exist in Squeak (ie the methods are still in SmalltalkImage), but the #os delegator is.

As SmalltalkImage isn't classified under Kernel, I don't think so.
Kernel vs. System categories is another debate :)

IMHO, they would be better replaced by Smalltalk os, but as I don't have time to do it myself, I won't complain they're not :)
