Hi Thomas,

A (very) quick answer...

No!

With :results raw, the raw output is inserted directly into the Org mode
buffer. This is a good option if your code block will output *Org mode
formatted text* (this will even be fontified as Org text you would have typed
yourself).

As there are *no obvious markers to delimit the results* in the Org mode file,
there is no way to know where raw results begin or end: raw results *cannot be
removed* from the buffer.

With :results org, raw Org mode results will be harmlessly *wrapped in a Org
mode block*. The "#+begin/end_org" block wrapper makes it possible for the
entirety of the results to be clearly located and replaced upon code block
re-evaluation.

Hence, not a synonym.

No. AFAICT:

- "wrap" will disappear (renamed as "drawer"),

- "drawer" is not the same as the old "org" option (as the results gets
  inserted into a drawer, not into a block).
