Couldn't you say the same thing for iOS/iPadOS though? It's up to the developers to manually support iPads. To date, very well known and popular apps like Instagram still run as iPhone-sized. Which is especially perplexing because there are seriously good photographers on Instagram whose work should be enjoyed on a bigger screen.

Google picks up and drops tablets semi frequently. It wouldn’t surprise me if the manager who came up with the idea of doing tablets again gets promoted and then the idea gets abandoned shortly after.
