Or you could just trim the URL yourself.

The problem on mobile devices is that URL bar is single-line and has like 30 characters length and , while query string crap is sometimes several hundreds characters long. It's not every ergonomic.

But yeah I often copy the URL to "notepad" app before sharing and trim manually.

Even worse is chrome on android now. You have to copy the url, re-paste it and then edit. You don't have immediate access to the url you are on.

Which is a behaviour I observed in most power users, but none in the non-power user group.

I don't think most non-power user even want to try to trim that stuff, because they don't know what can be trimmed and what can't.

Yep unfortunately true. I recently saw an official document from local CDC in my home country. There were two URLs "find more info at" in the document:

file:///C:/Users/blabla/something.pdf

httpx://who.int/something?fbclid=<200-hundred-chars>

This is also why most non power users will have chrome browsers loaded with tons of add-ons and basically let every site start sending notifications...
