To be honest, I do not find the combined library such a bad idea.
Actually I think that going this way has been discussed before,
long before Chromium existed.
For example, if you have to dlopen ffmpeg libs, it takes a lot of care
to load all the interlinked libraries in the correct order.
And imagine the fun if you have multiple versions installed.
Having one front-end to load all correct libraries is
logical improvement and simplification.
This is why Chromium has done it on their own.
This is why FFmpeg should do it too.
Also, the changes are isolated to a separate file in the build system,
it should not interfere with normal build process or merges.
I do however object on hardcoding "chromium" codepaths in it.
