I also prefer the NO-EVAL naming. I updated the patch to use no-eval and also 
added a second patch to rename the light argument of 
org-babel-get-src-block-info and all its occurrences (I changed the 'light to 
'no-eval in all its calls only for consistency and future proofing reasons, 
altough it is unnecessary right now). Feel free to squash them into one commit. 
I was not sure wether one or two commits would be preferred.

Thanks for asking. I use it in a function that creates quasi unique names 
similar to org-babel-temp-file. But instead of random names it uses the source 
block content and header info to create a unique hash. This makes it very easy 
to create unique but from call to call consistent filenames in header 
arguments, when you don't want to worry about the filename, but also don't want 
to clutter your result directory (especially if its not /tmp) or care about 
constant filenames, e.g. for linking. Without the no-eval/light argument the 
hash generation gets stuck in a recursive loop. I attached the functions for 
reference.
If there is wider interest in this, these could be added to org either as a 
variant of org-babel-temp-file or as an extension.
