And the new option should be documented at the top of the init()
routine for perldoc.

Added in the attached version.

Not much, so feel free to not wait for me.  I've just read through the
patch because I like the idea/feature :)
 
Thank you, that helped a lot.

Fixed in the attached version. 


I'm slightly concerned about 0002 that silently changes the meaning of
get_controlfile().  That would impact extension code without people
knowing about it when compiling, just when they run their stuff under
17~.

Agreed, now they will have an error as _could not read file "<DataDir>": Is a
directory_. But, IIUC, that what usually happens with the dev version, and the
extension needs to be updated for compatibility with the newer version for the
same reason.
