In pre-C23, _Static_assert and _Thread_local are keywords, and
static_assert and thread_local are macros that expand to those keywords.

In C23, _Static_assert, _Thread_local, static_assert, and thread_local
are all keywords.  Code that simply uses the old ugly keywords would not
break.

Code that does something like "#ifdef static_assert".  I suppose the
headers could have retained the old macro definitions.

    #define static_assert static_assert
    #define thread_local thread_local
