I wasn't proposing anything. I was just supposing.

What is a 'global log archive'? Do you mean a single file where all logs 
go? AFAIK you can set up syslog to log all messages into one file as 
well as per-service files. So the deal is just to extract configuration 
from syslog. Of course, if the services are using it, not keeping their 
own logs as is usually the case of apache. As a multiuser (multi-vhost) 
webserver admin I have to set up apache to log into users' home 
directories, so I even don't know how many user logs there really are. 
And I don't need to, because I've got my own global log. But a user is 
definitely more familiar with a text file he/she can download via FTP, 
than with a journalctl wrapper which he has to know how to use (and also 
be granted SSH access to use), at the least which parameters to specify, 
if at all usable in such setups.

I don't need such 'solutions' to non-existent problems. But if there 
were a *real* necessity to pretty-print a log's tail in service status, 
I think it would have been a matter of a proper setup (i.e. the service 
using syslog, hence a defined log format) and not a heck more complicated.

5 minutes is even too much to type sort of
tail -${LINES} ${SERVICE}.log
if you know where to look up LINES and SERVICE.
