I think it would be very nice to customize the service catalog page. Currently when you land on the page you just get a dump of every single request-able item. Some users will use the categories but most people will just scroll down the list. There are just way too many items for people to scroll. I believe if we can put the top request-able items on here, maybe top 4, then force people to use the search or categories on the side it'll be a lot nicer.
It's just like any e-commerce site, there is categories and then you can search down. No e-commerce site will dump all their products available into one scrollable page, it just looks ugly.
