Replace showpost link with permalink.

Hi -
I'm just curious... I noticed on almost every single review/critique from vBSEO staff the suggestion:

* Consider replacing your showpost link with permalink (a vBSEO option).

if it's that much relevant and everyone should consider it, Why is it not a default option ?

a) it was set up that was as part of the presets. changing the presets cannot be done, as it would break everyone's url's on update.
b) if it was set this way default, you know there would be 1000 threads about "VBSEO BROKE MY SHOWPOSTS!!!!!!!
