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.
