[928uk] 928 vs PK tensioner

[Adrian Langford via 928uk]

I may fit PK tensioner next time, as this time I just rebuilt original tensioner. But I can appreciate that the PK design eliminates some components (idler pulley and bushings to start with), and of course does away with need for retensioning. 

But I can't think of any way the original design stresses water pump, unless I'm missing something. I think there's a roundabout benefit in PK tensioner allows use of older/cheaper pump from earlier cars. 

iPhone therefore I am

Is there any consensus around the benefits of the PK tensioner to improve the situation?  It just seems very strange that we have had so many water pump related issues from so many vendors.  One can't help but imagine that the original design imposed abnormal stresses on the associated components.
