That must be new. My locally installed opera does full
zoom.

The usability problem with full zoom is that one gets
horizontal scrollbars 
very soon (especially on those 6pt default font size pages).
So one has to 
scroll back and forth to read big enough but then too wide
rows of text. 
Hence, for a web browser, font scaling can be considered to
be the "natural" 
action to be issued for Ctrl++/- which tries hard to fit
within the available 
viewport space.

This is an msie-extension to css [1]. Applied to an element
(block-level 
only?), this element and it's children are zoomed by the
given factor.

MAYBE. BUT ONE OTHER COMMON ACTION IS TO WORK AROUND THOSE 
ANNOYING "DESIGNED FOR 800X600" PAGES (WELL
"FIXED" 800), TO MAKE THEM USE 
THE SCREEN SPACE, INSTEAD OF MAKING YOU SQUEEZE YOUR EYES.
SO INCREASING 
THE FONT SIZE ONLY BREAKS THE LAYOUT.

WELL, THE LAYOUT IS BROKEN ANYWAY WHEN USING FONTS OTHER
THAN MICRTOSFT 
FONTS...
