It would be awesome to migrate the two current legacy monolitic httpd `/etc/httpd/conf/virtual.conf` and `virtual-le.conf` files to a Debian-like configuration e.g. splitted for each domain / for each project and tracking available and enabled websites.
In short splitting the configurations in this way:
https://phabricator.wikimedia.org/diffusion/WIIN/browse/master/servers/fabula/conf/httpd/
Also actually our VirtualHost(s) were defined in the following way:
```
<VirtualHost domain.tld>
ServerName domain.tld
```
That way is not optimal because it's resolved internally like:
```
<VirtualHost IP_ADDRESS_DOMAIN_TLD:80>
ServerName domain.tld
```
This means that we are making Apache HTTPd listening on a single interface (handling a single IP address) instead of listening whatever interface.
This also does not simplify some other stuff like {T274064}.
In short this can be fixed adopting this approach:
```
<VirtualHost *:80>
ServerName domain.tld
```
