I had converted my uses (tangling code, not text/documentation) to
this but I ended up reverting.

Some drawbacks:
 + doesn't work for all languages (does work for LaTeX)
 + the tangle gets very noisy: not only are the result of execution
   printed in the echo buffer, but emacs visits the tangling buffer
   and moves the point to each block.
   Perhaps this is a bug that can be fixed.
 + src block execution also resets the noweb cache, slowing down
   tangle, though I have not tried to measure the effect.

As stated in the OP, I find it unfortunate that org does not provide
any way to tangle the content of a src block to a string representing
this code. If anyone shows any interest, I've provided two possible
implementations in this thread, that I can rebase.
