You are right that a separate prompt will be shown for each eval form,
even when multiple :var assignments are present in the header arguments.

I could try to patch the higher-level function that is causing the
"pwned" in your example, but I figured that org-babel-read is actually
used in many more places and thus similar issue could occur in different
scenarios. Displaying prompt in org-babel-read is the safest approach I
managed to come up with.

What can help here is the feature request about bulk-yes/bulk-no code
prompts:
