I don't think 2017 was as impressive as it's made out to be but I don't really find the arguments in the OP compelling, especially when you mentioned announced but not released third party exclusives (Octopath and SMTV), but don't mention released third party exclusives (like Mario + Rabbids or Fire Emblem Warriors).

Thing is aside from those, and Rocket League + Bethesda games. 2017 didn't have that great of third party support for the Switch. 2018 was better in that regard as there were more companies supporting the system, and more games released regularly.
