I can agree to this, but if you consider a possible feature where Ada
is widely used as a standard programming language there would be
a need for libraries written in Ada, too.

If you only encapsulate the C-Code by some Ada-wrapper-functions you'll
get a huge amount of C combined with tons of Ada, doing more or less
the same.

Think of PostgreSQL: there is a thick binding, I need libpq for it,
but it works very well. Ok, that's what you're saying: it works, use
it and do something interesting with it.
OTOH libpq itself could be implemented in Ada. I guess you'll find
a wrapped socket()-function in it. If there is a better abstraction
we even can get rid of this by providing a direct kernel-Interface.
After all, no C involved.

Don't ask me why, but I think this is better. You can use the main
Ada-features across your libraries, you don't need to convert types
between C and Ada, get all the checkings and so on.

For sure, at the moment. But I don't want to have AdaOS with GTK written
in C. That's all :)
