It's not at all surprising that they'd plan on supporting it eventually. They may not care much about gaming performance, but they do care very much about power consumption in laptops, and allowing a monitor to save power by refreshing less often when it doesn't matter was the original impetus behind adaptive sync.
But it's still good news that Intel plans to support it, and I say the sooner the better. Industry standards that let you pick any monitor you want and any GPU you want and they work together nicely are a good thing for consumers. Support might be a ways off, as the GPU needs to have some things in place in order to support it properly. AMD's original GCN-based GPUs cannot support adaptive sync, for example, though the newer GCN architecture GPUs do.
