Taiob Ali has a set of hints to use instead of setting trace flags:
Introduced in SQL Server 2016 (13.x) SP1 and Azure SQL Database is the USE HINT option. At the time of writing this article, there are 23 of those. You can see an up to date list by running Dynamic Management View sys.dm_exec_valid_use_hints.
With the introduction of this feature, we can replace some of the trace flags with hints. I personally like hints over trace flags (if I have to choose between two devils). That way someone reading the code have some idea what the hint is about instead of remembering the trace flag numbers.
I agree with Taiob on that sentiment.
