I support Sitrec, but I do think there is one more concern: the current POM shader is not an official one. POM is one of the best ways to add depth, as far as I experienced it, and not having an official shader for this is kinda sad. The current one is, like Sitrec said within the other thread, more or less hacky. It would be nice to get a proper shader for this which is natively integrated into the engine, I see no disadvantages at all.
For anyone not familiar with POM, here you have a small comparison of the three current ways, I know of, to add depth:
