I'm just adding a few cents into this discussion for some inspiration. If
I'm not mistaken, the Twig template engine, for example, has such a
difference integrated in the output tag and the statement tag. The
statement tag ({% %}) behaves as PHP tag, it removes the newline character.
The outputting tag ({{ }}) adds a newline at the end.
See this: https://twigfiddle.com/pto9qx
More info about this here:
https://twig.symfony.com/doc/3.x/templates.html#whitespace-control
So, it is actually important to have such functionality in templates.
