Normally /etc/subdirectory.d is used by software that uses several 
configuration files, it can be one or more.  Usually it holds more than 
one.

From `man cron`

"
       Additionally, in Debian, cron reads the files in the  /etc/cron.d 
 directory.   cron  treats  the  files  in
       /etc/cron.d  as  in the same way as the /etc/crontab file (they 
follow the special format of that file, i.e.
       they include the user field).  However, they are independent of 
/etc/crontab: they do not, for example,  in‐
       herit  environment  variable  settings from it.  This change is 
specific to Debian see the note under DEBIAN
       SPECIFIC below.
"

This depends on the implementation of the cron system, as I see it seems 
they are using "Vixie Cron", which supports sending mails through the 
daily cron instances.  Hence they have added the control for environment 
variables for the cron daemon initialization, in order to control 
certain environment variables (LANG, LC_CTYPE, ...) in order to set the 
charset for the mails.

There are cron implementations that do not support sending mails by 
definition of their own design, instead I understand that it can be 
configured from the configuration file to send mails (as an external 
thing).
