Matrix conversions between RGB working spaces can be concantenated. That 
concantenation goes through XYZ. It almost sounds like you want to 
obscure this fundamental distinction between XYZ and unbounded linear 
gamma sRGB.

I do know what "implementation detail" means.

You didn't the question, so I'll try again:

Are you planning on converting non-sRGB images to unbounded linear gamma 
sRGB? Yes or no?

If yes, are you intending that at least some editing will be done on the 
image while it's encoded using sRGB primaries? Yes or no?
