That "slightly larger than 100%" value was used to fix a bug in a few
old browser-versions - Opera amongst others IIRC.
Through testing I haven't found the need to fix any bugs that way in any
browser for the last two years or so, so I use 100% flat.

Following official or "official" recommendations too closely may, IMO,
reduce our ability to make individual - case-based - design choices.
Having a number of well-working alternatives around would be good though.

That's what I call "em sized" and some call "elastic". It's working as a
"px sized page zoomed in Opera", and solves the problem you describe. It
may require horizontal scrolling if font is resized too many steps on a
narrow window/screen though.
I prefer a variant I call "Conditional Elastic", where window-width is
the limit. It's kind of a compromise.
Horizontal scrolling is rarely necessary, but text and stuff may be
confined to narrow spaces if the end user doesn't provide a reasonable
amount of window-width for it to scale on when subjected to font resizing.
