I think that any updates should try to keep the line that point is in
under point, preferably at the same window position.  In that case
editing would not usually be disrupted, just navigation.  Any unsaved
editing operation in progress can continue as long as the file name
identity is not changed (if the file disappears, that would be reason to
throw an error and abort pending editing changes on that line).
