Based on my personal experience with WCCP (over 6 years). PBR is VERY
router's CPU consumpted.
WCCP - is not (L2, not GRE. GRE performs on CPU, L2 on control-plane and
hardware-accelerated).

However, using edge router for WCCP is not so good idea by another
reason. It breaks good network architecture in most cases. I'm not CCA,
but ever for me it's obvious.

So, underlying aggregations switches is more appropriate target for
WCCP, because of they can be uses L2 WCCP - which is extremely fast.

Depending of router. Branch router must have. Just take a look on whole
Cisco's router's range. Just for interest.

Cats delicious. You just do not know how to cook them :)

WCCP is a very simple protocol. While there may be poorly documented.
There is another problem - very few people well versed in networking
technologies, few details delves into what makes. The vast majority
simply copy-paste configs without a single thought in his head, not
bothering to understand.

What is there to maintain? Just configure it once and sit on the ass
straight.
