I had not thought of it. Can + also be a valid character?

'rest' (=) is equivalent to the rest of the backends that have not been
explicitly set. What happens is that, with my current approach, if you
want to export only one backend, you must enter:

:export backend =- (that is, export this backend and not the rest)

This is not ideal. It should be enough to just put:

:export backend

but I am not able to achieve it.

OK. How about the following?

- Single characters (they affect everything, if backend name is not
  specified, or the rest, if backend name is specified:
  
  * content
  / skip
  . never export derived backends
  = full, this and derived backends (default)

- And in combination with backend names (some examples):

  :export latex* > content to LaTeX, normal to the rest
  
  :export latex/ > do not export to LaTeX

  :export latex. > do not export to LaTeX derived backends

  :export latex . > export normally to LaTeX but do not export the derived 
backends in the rest of the cases

  etc.

These days I'm going to be a little short on time, due to work, and I
don't know if I'll be able to attend to the list. I want to calmly take
a look at the code you share.
