--- Comment #12 from Carlos Rafael Giani <dv at pseudoterminal.org> ---
But this is what the INFO level is there for. WARNING is for *abnormal*
behavior. Also, as said, the spec itself states that the padding header does
not contain any valid data. Stripping it is perfectly OK in the spec. The only
situation where it might cause an issue is if the user wants to preserve the
size of the padding header for some reason (typically during editing). Worst
case, the padding header is stripped, metadata is expanded later, and the
encoder/editor has to perform more I/O work (because it has to shift the
succeeding audio blocks further outwards to make room for the extra metadata),
and perhaps a new padding block is generated. But no information is ever
actually *lost*.
