We are in a rabbit hole with PyPdfium2 and trying to get redaction properly working . Analyzing how you did , you did a great job to get redaction working by forking pdfium and implementing redaction logic inside there. I am wondering if it is possible without actually forking and building it as a separate library since it would be great deal of work to maintain Pdfium C library to keep things up to date?

We are trying to get it working with pypdfium2 so , i think if thats possible would be easier to maintain for everyone .
