+1 for Bun integration.
I understand that you focus on demanded features, but Bun seems to be kind of a no-brainer.
It's a drop in replacement for node which is faster, has build in support for TS etc.
For me as a lead developer, I supported the use of server with Plesk in our company, because of it's great support of NodeJs, which allows us to deploy Node-Apps in minutes. And through this decision many other Devs in our company worked with plesk and they want to use it in the future.
It might seem to you that it's to early to care about Bun integration, but there are many other developers who decide which server stack will be used in companies and many of them will use Bun. If you show the Dev community that you are at the edge of the time it will definitely help Plesk.
