On the Beethoven, just because he didn't write all the pedaling in doesn't mean he didn't think you should pedal as your taste dictates. Composers mostly assume that a performer will have some discretion. Those that don't allow that (mostly much later) are simply wrong. Instruments vary, rooms vary - so absolute tempi, pedaling and so forth can't be set in stone, they have to adapt to the circumstances.
Besides, I think Mr. Beethoven would be the first to support artists who dared to add something of their own when performing someone else's compositions ... just like he did! After all, if we were supposed to follow the directions in the notes in every tiny little detail, we could just as well let computers do the playing.
