Hmmm,
Recently I started to use source code blocks as a kind of init for a
certain task,  set variables,  modify stuff.  That is,  execution of a
source code block once at the beginning, e.g.  after opening an org file.
Thus, I was thinking about automatically execution too.
Would it help if there would be a approval necessary by the user.  A list
of trusted organisation files could be compared to execute a start block
without approval.
Sure there are still possible attack scenarios but that's what you pay for
more comfort ;)
