Any plans to include support for Synapse Analytics serverless pools into Pulumi Azure provider? Or am I just blind and can't find it from docs or code?

I’m not sure. You can try creating it manually and see what the Export to Template button shows?

It looks like Azure Synapse creates the serverless pool by default these days. So, you do not have to create a pool at all, it's there. That being said, setting collate into correct setting is a bit tricky this way but oh well
