I'm deeply glad MS is contributing not controlling, given the declining state of MSSQL. Maybe it'll motivate them to pull their socks up over their own flagship product.
what is declining in MSSQL? last 3 years were an absolute gamechanger for my use cases: dockerized linux option for linux testing, very helpful columnstore improvements, the HA story is quite impressive, in fact there are only two major drawbacks that i can tell: no command line tool like pg_dump and the awe-inspiring price of the license (though i hear still less than oracle).
There's plenty more low grade shit in what was once a goof product.
I haven't used the features you discuss but then I need basic functionality to work. I've run into stupid performance bugs with trivial CTEs, and I found a link showing a CTE error which I could duplicate (pgres got it right, mssql didn't). Can't find link, sorry.
The cost, god the cost has got so much higher. I love SQL Server but am being forced off it, especially as you need enterprise to do queryable replicas etc.
