How to remove Chromium PDF Viewer extension?

[rphair]

Is there a reproducible way we can remove the built-in Chromium PDF Viewer extension (mhjfbmdgcfjbbpaeojofohoefgiehjai)?

I know that running this extension for its intended purpose can be disabled with Settings > Privacy and security > Site settings > Additional content settings > PDF documents > Download PDFs but I would rather remove it because of the permissions granted to this extension ("elevated" private permissions, indicated at the link above) plus the fact that it's been blacklisted in Brave browser (which I have to assume is for security reasons unless proven otherwise).

Although I would rather have it gone, I'd be also happy with the maintainers' or contributors' assurance (and reasons) that this extension doesn't have any closed source components or other security reservations. 🙏

It is probably doable, but requires lots of patching. I tried at some point in time, but gave up. See here: PF4Public/gentoo-overlay#26

Thanks @PF4Public - with that in mind, I mostly wonder about the second part of this question: whether the built-in PDF extension, or the code behind it, could qualify as a security risk. 🤔
