Thanks for the proposal!

C-c C-c mechanisms and preview mechanisms are very different things.
C-c C-c is supposed to _run_ the code. Inserting overlays is a rather
fragile side effect of running a code.
So, utilizing preview does make more sense compared to utilizing babel.

However, I am not very sure if previewing raw svg fragments is something
many people will need. At least, I do not recall many requests to have
previews of svg images _specifically_. AFAIR, the more common requests
are (1) previewing html links and files (for example, produced by
ipython); (2) previewing base-encoded images in general, not just svgs;
with the intention to store images as plain text, right inside Org
buffers; (3) previewing pdfs.

Rather than adding a new preview command for each possible data type,
I'd prefer to see a more unified API to preview parts of Org files.
So, your idea to integrate things with the existing image latex does
make sense.

However, we are currently in the process of major rewrite of the latex
preview system [1], so making major changes in this area is temporarily
suspended.
