You need to add 0.5 to the "label Chrome" above to get it to generate the api.

Also I'm curious what the background is behind this being deprecated?

This was only used to implement the SRPC NaCl proxy.

Even with 0.5 label above, the generator won't generate the code, until you add
another function for 0.5.

Interesting. It worked for me when I recently revved the flash interface but I
have definitely seen it not work in the past. Anyhow it is no big deal for now
since we aren't deprecating the function.
