I asked this question because on my laptop there's an alternatives system
that can keep several programs providing the same or similar functions
at the same time.
Debian also has an alternatives system but doesn't allowed to install
multiple MTAs. 

https://github.com/fedora-sysv/chkconfig/blob/master/alternatives.c
$ dnf info alternatives
Name         : alternatives
Summary      : A tool to maintain symbolic links determining default commands
URL          : https://github.com/fedora-sysv/chkconfig
License      : GPLv2
Description  : alternatives creates, removes, maintains and displays information about
             : the symbolic links comprising the alternatives system. It is possible
             : for several programs fulfilling the same or similar functions to be
             : installed on a single system at the same time.
