Comment:

 afcowie: I don't think there is a consensus to remove the current check.
 Please use #6017 for further discussion.

 For reference, this feature was introduced 14 years ago, in commit

     - only read ~/.ghci if it is owned by the current user and isn't
       writable by anyone else.

     - Only read ./.ghci if both . and ./.ghci are owned by the current
       user and aren't writable by anyone else.  I think this is
       sufficient: we don't need to check .. and ../.. etc. because "."
       always refers to the same directory while a process is running.
