It's receiving good support at the moment but so did HD rumble when the Switch launched.
Nintendo killed hd rumble and other Switch features with the release of the Switch Lite. Considering 3rd party devs probably knew about the existence of hd rumble earlier than us, its not really surprising they didn't use it. For now people are excited about it in no small part thanks to Astro and Demon Souls. So I wouldn't be surprised its hear to stay.
Please excuse my (probally) poor grammar
