I think it's important. But I also think some people on the internet treat it as being more important than it actually is.
IMNSHO, it's not something that is easy/proper to strive for directly. Rather, it's something that happens naturally when other things are working together well. Once you get the other problems worked out, it's part of the net positive results. The whole that's bigger than the sum of the parts. Or something along those lines.
