Yes, makes sense.

Just wondering how could be some real world cases, for example:
Postfix:
master_config_file_template  (master_cf_file_template? master_cf_template?)
main_config_file_template

Apache:
httpd_config_file_template? or config_file_template?

Vsftpd
vsftpd_config_file_template
chroot_list_config_file_template
banned_email_config_file_template

Some cases might become ugly...

One good of a standard, prefix-less, name for the "main" configuration file would also make modules cloning quite quicker (and therefore also somehow an easier user experience (you always know that the main config is managed with a standard param (be that template, file_template or config_file_template.... )
