I can speak for myself that I religiously follow the convention to use #'SYMBOL instead of 'SYMBOL where SYMBOL is expected to be a function in the form where it's used; exactly for the reasons that Stephan mentioned. In addition, to the user it becomes evident if that symbol is expected to be a function or not.
I use that convention in my emacs config, packages, etc. I have even seen that convention in many other packages and configs too, from what I follow on emacs.stackexchange, reddit, etc.
This is a very popular post out in the wild, by Artur Malabarba that explains why and when one should use sharp-quotes or hash-quotes.
If we are counting votes to add this to the official documentation, my vote is in :)
