Hey, glad you liked the post. All these services that have been popping up around JAM approaches are really great and help so much with adding extra functionality to our applications without the need for complex microservices set up on a first party level.
Complementing your note on e-commerce, there are an increasing number of solutions around checkout journeys and carts for JAM/static sites, another example I recently came across is Foxy, formerly known as Foxy cart.
I used e-commerce on my talk/post as a potential challenge for JAM more because I often hear people trying to use it as an argument against using JAM but that does not seem to be the case as much anymore.
