Fine with me.

Not sure what you mean: the variables I mentioned are AFAIK documented
in the Emacs manual.

IMO, this should be brought up to the attention of the Org developers.
Org mode has special needs when non-relative line numbers are
displayed, and the solution should IMO be in Org, not in Emacs core,
because solving that in core would mean significant run-time penalties
for everyone who uses line-number display.  I'm sure that these issues
can be quite easily fixed on the Lisp level by Org mode itself.

Thanks.
