These companies have different opinions on the reason why they reject links.
I don't think that helding too many audits makes sense, because, as you noted, we successfully ignore the links, and if we see that the links are of an organic nature, it is highly unlikely that we will apply manual sanctions to a website.
Therefore, we do not see the full benefits of scanning HTTP / 2.
But with more websites implementing push notification feature, Googlebot developers are on the point of adding support for HTTP in future.” It should be recalled that in April 2016, John Mueller said that the use of the HTTP / 2 protocol on the website does not directly affect the ranking in Google, but it improves the experience of users due to faster loading speed of the pages.
Oct 08/2017 During the last video conference with webmasters Google rep called John Mueller said that Googlebot still refrains to scan HTTP.
The reason is that the crawler already scans the content that fast, so the benefits that the browser receives (web pages loading time is decreased) are not that important. We are still investigating what we can do about it.
According to Gary Illyes, auditing of links is not necessary for all websites at the present moment.
"I talked to a lot of SEO specialists from big enterprises about their business and their answers differed.

This information was reported by Jennifer Slagg in the The SEMPost blog.
Since Google Penguin was modified into real-time update and started ignoring spam links instead of imposing sanctions on websites, this has led to a decrease of the value of auditing external links.
Therefore, we believe that counting the exact number of algorithms that Google uses is not something that is really useful [for optimizers].
From this point of view, I can’t tell you how many algorithms are involved in Google search." Oct 08/2017 At the Brighton SEO event that took place last week, Google rep called Gary Illyes shared his opinion about the importance of auditing the website's link profile.
In general, the difficult part is that Googlebot is not a browser, so it does not get the same speed effects that are observed within a browser when implementing HTTP / 2.
