The issue of lineage MAY be a valid one when the question of a legitimate successor is important.
Beyond that, I have no idea WHY it would matter to anyone else.
Truly.
I read this and agree with it 100%:
"Tradition is the living faith of the dead; traditionalism is the dead faith of the living. Tradition lives in conversation with the past, while remembering where we are and when we are and that it is we who have to decide. Traditionalism supposes that nothing should ever be done for the first time, so all that is needed to solve any problem is to arrive at the supposedly unanimous testimony of this ****genized tradition."
-Jaroslav Pelikan
The crucial part in this, IMO, is this part:
"...while remembering where we are and when we are and that it is we who have to decide."
So much would be so simply if people would realize that.

Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
