I think you're still going to have trouble with commands which can modify multiple lines. What will you do to handle global search-and-replace via ":%s/pat/rep/g"? Or multiple-line delete with either "10dd" or ":123,456d"? There are too many ways to modify lines to protect a specific range of lines from all edits, which is what I'd expect from a "read only lines" feature.
