You are not alone. It's further back on said to-do list, as it appears to be a problem with no easy existing solution, and it's too big of a project for the immediate payoff.

If you happen to stumble upon a solution (obviously self-hosted/local, due to the unfiltered access to page content), I might be willing to contribute with configuration scripting or client/server splitting so that the bulk doesn't have to stay on e.g. a laptop.
