Possibly, only if edits would send notifications, and you could tell what new information was introduced.

Things like system identification, and the text like you mentioned should allways be put in the question. But I have seen some new users do running edits to posts (with information best suited to a comment) without informing users or answer posters, causing people to down-vote answers, that seem to have already been tried by the user (when it was an edit to say they tried the specific solution).

Also to help users, when asking for specific information or clarification, say to edit the post so it is clear to new users.

Edit: here is an edit on my answer (may be diffrent with questions?) to test this out, did you get notified John

Also do you check the edit history when voting on a question and answers?
