Comment (by eschnett):

 The difference between {{{: >FILE}}} and {{{echo 1 >FILE}}} is that the
 former creates an empty file, while the latter writes something into the
 file. Writing an empty string (as you suggest) is also fine, but is the
 same as just writing {{{echo}}}, as both simply write a newline character.

 I don't see a downside, except (tongue-in-cheek) the increase in build
 time for calling {{{echo}}}, and the increase in disk space for creating
 non-empty files.
