Apparently this is in preparation for the new "Proton UI", which is one of those things the design teams in big companies do to justify their existence.
I just downloaded Nightly, which already has the Proton UI, and indeed compact mode is hidden behind an about:config option and it's a bit taller than the one featured in the current UI. I really can't fathom why this has to be the case.
