Hi Nikolay,
Thanks for having interests on this. Although I have never experienced the problem you described, capping the acceleration or tweaking the factor in some way do make sense.
As for how to get this merged, there are probably more works to be done than I anticipated. In !426 (comment 617988) Peter stated that he wanted it to be a separate profile, which makes sense. However, as discussed in !426 (comment 731737), besides landing it as a separate profile, we'll have to change the compositors to actually make use of the new profiles. Otherwise, there will be no ways for users to select the new profile.
Besides being unable to squeeze out the time needed to finish all these tasks, another unfortunate thing is that I no longer have a laptop running Linux. (I mainly use a workstation with a mouse now.) So it is not so realistic for me to continue working on this and test it thoroughly. Thus I'll probably close this. But, if anyone wants to take this on, please feel free to open a new MR and take whatever you need from this.
