I have been making the same recommendations about tempdb since I started working with SQL Server over 15 years ago, when I was working with customers running version 2000. From the customer side, this has been the limit of what can be done*, until SQL Server 2019. Pam Lahoud also did a quick demo in her PASS Summit general session.

Despite the name, serverless computing still uses servers. This means companies can access the exact resources they need whenever they need them, rather than paying for server space and computing power they only need occasionally. If servers reach maximum load and capacity in-house, something has to give before adding new services.

This was convenient for the demos but repeatable read isolation isn’t common in everyday use. When SQL Server reads data under locking read committed isolation (the default for non-cloud offerings) and chooses row-level locking granularity, it normally only locks one row at a time. SQL Server solves this problem using lock classes.
