You can't work on just the content stream level, even with just text. Why? Because you need to ensure that nothing else moves when you remove something. And sometimes the positioning operators are relative to the current pen AFTER drawing, for example consider: 1 0 0 1 100 100 Tm (See) Tj 50 0 Td (Jane) Tj 25 100 Td (run) Tj And you want to remove "Jane" - you can't just remove that one line - since now "run" will be in a different place on the page. And you can't know how to adjust the positioning of "run" without being able to load fonts, measure text, etc. iText has a lot of great stuff in there - but not all of it is necessarily exposed as needed for this task.
