As I said, this would add an indirection level to an already complicated

Moreover, toggles in the export interface are never duplicates from
in-buffer settings, so far. This would set a precedent, and might be
a sign that this isn't right.

Why would you add :eval no-export to every block in the first place? In
this situation, there should be a global setting, which could be
overridden locally with appropriate header arguments.

Having a global way, even dynamic, to override every setting in the
buffer doesn't seem very useful. It is imprecise; some blocks could
still be used to set up export process. I assume there's a good reason
if a source code block specifies :eval yes.

I think the starting point is in (info "(org) Exporting Code Blocks").
Improvements to the manual are welcome, of course.
