It is not that easy just too look at ports. I give you three examples 
from work:

1. Zabbix (network monitoring), suppports only SMTP, although PHP 
supports sendmail(8)
2. JavaMail Transport implementation exists only for SMTP, I was not 
able to find any transport implementation for sendmail(8). Maybe I will 
write one for fun.
3. Python mail package supports SMTP only, no other package available, 
at least AFAIK.

Unless ecosystems provide impls for sendmail(8) I see it very hard to 
live without localhost:25 for many cases.
