I don't care for it, but don't feel as strongly about it as you do. It is too crowded and busy. I like the option to collapse them as stated in bullet point 1 of #109.
I have been reserving judgement. It has that same "early 2020's" feel to it that the foundation page has. Whilst this probably appeals to many, it ends up losing the "academic quality" look. Fitting in with the classic UNIX research papers kept a real consistency that Linux could never achieve. However, since visual trends tend to cycle every decade, I am sure we will be back to that.
Since a pdf can be generated, I have no real problems with it, though I would say the biggest issue is that now it makes the main freebsd.org website look out of place and inconsistent; almost appearing like the foundation page is the main portal which it should never be.
That said, I am impressed by carlavilla@'s efforts. It seems like a lot of work and design aside, it is looking very complete. Anything is better than a half-finished documentation portal (i.e Alpine, Debian Linux, etc).
