I think you can ignore that without fear.
It makes me laugth how amplified are the otherwise minute changes discussed in forums and articles.
You sink the front by 10mm, at a distance of let's say 1500mm (wheelbase is 1415mm) from the rear axle.
That's 1/150 or 0.38 degree (of rake). See what I mean?
The preload, how much fuel/luggage you carry, your weight, your position, even tire wear, could all change how low the triple clamp is, by more than 3/8"...
If that really mattered, I would simply dial in (add) preload to raise it a bit, rather than a costly visit to shop.
