Maybe you have missed the proposed new seeking API

anyway, i dont think your patch does anything beyond that it would
break seeking in the few formats where it works currently
If you can explain some positive effect beyond that iam all ears
making function A behave like function B of course not a positive
effect as such.
and changing the regression test checksums should really raise a red
flag, the effect of this wil be vissible to the user as seeking will
