While true it was a sop for Lasseter, I would think that it's unlikely to be undone anytime soon, or the practice to go away.
Since Disney isn't devouring Pixar, but letting it stand as a separate brand, then it's going to promote "Pixar™" like it promotes "Disney Princesses™". And they'd be crazy not to, considering how well that brand performs with customers and with revenue.
With the mandate for IP synergy in the parks, there's eventually not going to be any attraction left that isn't connected to an IP. So, if they were to de-Pixar the Pier, then it would be to only add some other IP, such as Dumbo's circus.
When people were advocating for a Pixar Land in DHS, I'd be arguing against it since "Pixar" isn't a theme. But they were all doing mental gymnastics to make it fit. Well, there's now a Pixar Land in DCA. On top of that poor overall theme, it was implemented very shoddily and cheaply. And it looks like DHS is slowly gaining a Pixar Land with Metroville and a Cars attraction and a Monsters M&G orbiting Toy Story Land.
If Disney can learn the lesson of Cars Land and Toy Story Land and make a 'land' based on a single, good Pixar IP, it can continue to do good. But if they're going to clump disparate Pixar IPs together to make a "Pixar Land", then we're going to hold onto and keep getting more "Pixar Piers" unfortunately.
