Here's a little bit of trivia... The Visualforce framework (that customers can write interactive pages in, and a small minority of the standard UI is build in) is based on JSF, but most of Salesforce classic standard UI is written in a home-grown system that generates HTML described in imperative Java. It's more akin to an HTML generating Tk.
> the team now functions as an internal infra team for Salesforce
This is definitely false. Though some internal apps are deployed on Heroku, it is not the primary deployment target for new projects. Heroku staff work on Heroku. Salesforce has a large internal infra program and team that has no overlap with Heroku. past codename projects have been proposed to change this, but none have ever come to be.
Periwinkle never materialized. Neither did Shinrai, or a number of other projects that people brought up in hn threads about this incident. It’s clear that Heroku has lost a ton of great talent and momentum due to questionable business decisions but some of the most controversial fail to ever make it past codename status.
