Feedback on "Replace the silicone nozzle ring"

[KickahaOta 14]

I recently went shopping for print cores (please stop me before I shop again), and noticed that the new ones do not have the silicone ring around the nozzle. This led me to https://ultimaker.com/en/resources/50885-replace-the-silicone-nozzle-ring .

 

A couple of thoughts on this page:

• It's striking that Ultimaker has shifted from 'These rings are important enough that we include ten of them in the maintenance kit' to 'These rings are unnecessary and you can throw them away.' This seems worth spending a couple of paragraphs on 'Why?' What purpose was the nozzle ring intended to serve? Why is the ring no longer necessary?
• Saying "If you still have spare nozzle rings, you may choose to use them or throw them away." -- and leaving it at that -- seems a bit odd. If Ultimaker's position is 'Sure, if you feel like using them, that's fine,' then the instructions for how to use them should still be included. If Ultimaker's position is now 'You shouldn't use them,' then omitting the instructions is appropriate; but in that case you should probably come out and say so.

 

Thank you for your consideration.

I totally agree
