Until one goes bad and/or you have to trace one.
I was the guy who had to do that for over 20 years.
I used to save all the zip ties I had to cut off and dump them on the wiring supervisor's desk.
One year I also included a cost, so he knew how much we were throwing away.
I believe I also included a man hour breakdown as well.
It's only a few minutes per, but when coupled with a thousand or so zip ties, it adds up.
Not to mention the additional down time.
"Pretty" absolutely can NOT take precedence over "functions", and "able to be effectively and efficiently maintained".
The same guy would spend money to fill up the racks with blanks
before any equipment was installed.
The typical lifespan of about 40% of them was less than a week before my team removed them to install switches and servers.
Most got either thrown away or stored in the back of the back supply room, never to be seen again.
But new ones would be purchased every time a new building was built or a new rack installed.
