log_progress_msg overridden with empty function in /etc/lsb-base-logging.sh

[mc5686]

Binary package hint: lsb-base

The functions in /etc/lsb-base-logging.sh override all the corresponding functions in /lib/lsb/init-functions.
In particular it override log_progress_msg with the following code:
===========
...
 log_progress_msg () {
    :
}
...
===========

There is really little surprise in the fact no output is given.
Is this behavior intended?
If so: why?
fixing this is rather trivial, bu I would like to understand the "why" before touching anything

If that's relevant:
===========
mauro@heimdall:~$ lsb_release -rd
Description: Ubuntu 8.04.1
Release: 8.04
mauro@heimdall:~$ apt-cache policy lsb-base

UPDATE:
I changed my /etc/lsb-base-logging.sh to "fix" the problem (if any).
If someone is interested these are the diffs:

They appear to work correctly at least within gnome-terminal and at the linux console.

Progress reporting is handled via usplash, so this function has been stubbed out. It might make sense to rearrange things to call progress via the lsb scripts and detect usplash like the others do.

Also noted in Ubuntu Server 13.04

Still is in Ubuntu 14.04

14.04 this time it's directly in /lib/lsb/init-functions.d/50-ubuntu-logging

about line 86
log_progress_msg () {
    :
}

It's so difficult to fix Canonical ?? If you want to use your function call it from there then why is this ":" in body ??? to track how many users will complain about this and do some statistics? Who you are working for?

ok sorry I think that this is static, but should be a progress .. it's not simple then, but anyway for me I've used this code as static text to see at least some output and not to kill script in the middle of execution:

log_progress_msg () {
    GREEN=`$TPUT setaf 2`
    NORMAL=`$TPUT op`
    printf " $GREEN*$NORMAL $@" || true
}

Still in Ubuntu 16.04.4 LTS server
