Yes, it would be good to have that...

But why do you dislike the limitation? Do you think extensions provide
useful information? I suppose one problem is that *.bin might pick up
private blobs that happen to be in the source directory?

I would quite like the 'non-output' file (i.e. things that are not a
binman image) to appear in a 'binman-work' subdir of the output dir.
What do you think?
