Not exactly...

It's true that File::Temp sets the mode of the file explicitly, because
it creates the file as 0600 (at which point umask would be applied) and
then explicitly does a "chmod 600" (overriding any effect umask would
have had).

touch does not let the system *set* the permissions.  touch creates the
file with 0666 and lets the umask *remove* permissions.  A umask of 0002
does not mean "apps should create files with 0664", it means "if apps
create files, remove o=w permission from them".  It's up to the app to
decide what permissions to use when creating the files in the first
place.
