Conversion from jpg to webp removes EXIF metadata

Simple conversion from jpg to webp removes all metadata, is it possible to keep it?
Look's like cwebp can keep it while converting to webp from different formats.
-metadata string
A comma separated list of metadata to copy from the input to the output if present. Valid values: all, none, exif, icc, xmp. The default is none.

Note that each input format may not support all combinations.

We currently don't support this but I created an issue for it here: https://github.com/ImageMagick/ImageMagick/issues/291. Hope someone will add this for us :)
