It is not compatible with many convenient GTK APIs, for instance
Gtk::Action::create_with_icon_name.
Yes, it *IS* compatible with all of those GTK APIs.
I have seen it working with my own eyes
Did you even bother to test any of your assertions, or are you just
making blind guesses???
There is no way to convince
Gtk::IconTheme to fetch named icons from the monolithic file. One
can define
stock icons for every icon used in the application or add builtin
icons to
the icon theme, but those approaches don't work with scalable icons.
Please review the code that is in play when icons.svg *is* used. It
does use the theme mechanism. Your assertion that there is *no* way
to do this is not true.

They are a workaround for systems that don't have librsvg at all,
and I
don't like it. The real solution is to either bundle librsvg on those
systems, or write another GdkPixbuf loader for SVG that will use our
renderer. Those are the only ways to be able to use all the
convenient APIs
for named icons. I would opt for the former because it is much less
work and
has superior performance (librsvg is quite fast, in my tests it was
even
slightly faster than loading PNG icons).
No... those are *not* the only ways to do that.
Again, the current icons.svg file code *does* work with icons,
falling back, etc.
Here too is another key point I need to stress. You keep ignoring
this. Please listen this time
WE CAN NOT USE LIBRSVG TO GET FULL FEATURES OF SVG!!!!
That is *BY DESIGN* of librsvg. They have improved many things
recently, but they are intentionally *not* targeting full SVG support.

When I extracted icons from icons.svg, I had to modify exactly one
icon
(randomize.svg). And in fact it was just fixing malformed markup
that was
interpreted by Inkscape as correct. By the way, all other SVG icons in
existence are also "dumbed down" for librsvg, yet there are some
beautiful
icon sets out there, so the limitations can't be that severe.
No...
Here is another key point.
They did not break for *you* but they *DID* break for other people.
Please keep in mind that not everyone will be running the latest and
greatest versions of all libraries. You *must* keep cross-platform
support in mind for any code work you do on Inkscape. One of our key
promises is good cross-platform support.
