Comment (by schlessera):

 I've run this simple change through the profiler.

 I've done 3 50-samples runs on an empty site against the `wp-
 json/wp/v2/posts` endpoint. This gave me these numbers:

 {{{
 Wall Time     124ms   -14ms  -13.0%
 CPU  Time     118ms   -13ms  -12.2%
 I/O  Time    5.97ms -1.46ms  -32.3%
 Memory       2.72MB   -648B     n/s
 Network         n/a     n/a     n/a
 SQL          4.67ms    13rq
 }}}

 {{{

 {{{

 CPU  Time     119ms   -11ms  -10.7%
 I/O  Time     6.4ms -1.02ms  -19.1%

 Even if these numbers are not 100% accurate, it should be safe to assume
 that this change is an improvement.
