iPhone 15 Pro Max high or low amplitude vibrations

The support article Exposure to vibrations, like those generated by high-powered motorcycle engines, might impact iPhone cameras (https://support.apple.com/en-us/102175) - Apple Support is vague on this issue, especially the statement "It is not recommended to attach your iPhone to motorcycles with high-power or high-volume engines due to the amplitude of the vibration in certain frequency ranges that they generate."

Situation: I replaced my old 8 Plus with the 15 Pro Max. I have a 2010 H-D touring model with a 103 ci (1688 cc) Twin Cam engine (last gen before the M8) with no modifications; vibrations through the handlebars are very low at speed, but considerable at idle. I do not consider it "high-power" but it is "high-volume". I used a Ram handlebar phone mount for the 8+ and a 6 before that, each with "cradle" brackets and I never had a problem damaging the phones (the 8+ has OIS). Now, I want to use the same mount with an X-bracket for the 15 PM.

Questions: 1) Since the 15 PM has both OIS and AF, how are those systems "degraded" by high-amplitude vibrations and is there a phone setting to "lock" moving parts? 2) Are the effects of high-amplitude vibrations cumulative over time ("... avoid regular use for prolonged periods to further lessen the risk of damage."), or can damage happen at any time? 3) Why are only "lower-amplitude vibrations" less likely to damage the phone if using a vibration dampening mount?

Since there is a dedicated Support article, I assume that between Customer Support and Warranty data, the word "motorcycle" and terms "off road" and "OIS/AF damage" were common enough to generate an article, in part to help deny Warranty claims. While I understand this in theory, without Apple providing the frequency ranges of both high and low amplitude vibrations that cause damage, how is one to know?

CYA up-front and not buried in Terms, I like to think that Apple products are rigorously tested in many ways, including vibration, to ensure quality so the data is (should be) available and published. 

Some phone mount manufacturers offer vibration dampeners which I questioned with the similar vague information (in Ram's case, "Dampens Wide Range of Vibration Frequencies). This journey started with me questioning the meaning of that statement. In their case, the product is for many different brands/models of mobile devices, used on many vehicle applications; in the end, they were not sure of the 15 PM vibration parameters (because they don't know) and hung their hat on "wide range". When I questioned this statement on their Web Store "Exposure to vibrations, like those generated by high-powered motorcycle engines, might impact iPhone cameras", they sent me a link to the article and here we are!
