Comment 1 for bug 2071468

> Proposed solution: Add support for an `--escaped-package-metadata` parameter to the linkers that takes an URL encoded (RFC 3986) parameter.

It took months and a huge amount of fighting to get the option merged in all linkers, it was extremely hard. I am afraid this is just unrealistic.

The opt-out is there exactly to skip problematic packages, I recommend to just use it and skip those packages that are not doing standard debhelper builds. It's a small percentage nowadays anyway, so it's fine to just skip them.
