Configuation templates were left out of standardization many years
ago.  There was no interest to standardize configuration templates
(perhaps companies needed ways to distinguish products or finding
agreement on a standard template format was considered too hard and
time consuming or ...). RFC 8342 (published March 2018) acknowledges
the existence of configuration template mechanisms but also notes that
they are proprietary:

   o  Some implementations have proprietary mechanisms that allow
      clients to define configuration templates in <running>.  These
      templates are expanded automatically by the system, and the
      resulting configuration is applied internally.

The question is whether it is possible now (starting in 2024) to
define a standard configuration template mechanism that has a chance
to be implemented widely. See also the YANG next issue #18 (opened on
2017-03-17).
