key thing for me here is: why did Salesforce buy Heroku? How does Heroku fit into Salesforce strategy?

When Heroku was incorporated by Salesforce there was no consumer facing capabilities in SF: everything was for business/sales users so Heroku was attractive to build public facing assets seamlessly connected to SF data (hence Heroku Connect). But then SF started incoporating other consumer facing featuers: Communities, Commerce (Demandware), heck they even have their own CMS now. One can predict they will push lowcode/citizen development beyond Force.com. Where does that leave Heroku? What does it bring to the table now for Salesforce?
