Idea regarding GIT

Dear all,
I'm emailing to suggest feature for git. It can be useful for ppl working
with pipelines and having extensive personalized configs. I propose adding
new configuration file (or parameter in .gitconfig) .gittemplates. Files
listed in there had to be indexed before adding them to that file, otherwise
it would work like .gitignore, but difference is if file was added git will
not track changes in it and won't commit them. It can be useful with .env
files, using this feature their empty, template version can be committed and
frozen where local version can be edited. Same with configs requiring local,
machine specific paths. Now there is need to keep template version committed
with different name and proper one recreated locally and ignored which adds
extra work each time. 
Thanks for ur time, lmk ur thoughts.

Kind regards,
Kris
