In your opinion. But if I typed a character, I would already know what key I just typed. And at top of file and line beginning, after the insertion point makes more sense. So not silly.

Furthermore the only difference between an insertion point cursor and a block cursor in Qt is cursor shape, i.e. it is not a mode indicator. So "under the cursor" should indicate the char after the insertion point, which in Qt is also the character at the textcursor start position in my opinion. The most common use case is investigating strange diacritics, rare punctuation, and special whitespace chars and for that either before or after the insertion point works.
