There is an issue related to this here:
https://github.com/w3c-ccg/did-method-key/issues/32

I believe the compressed and uncompressed form can be converted back and forth without loss of key information. Hopefully the specifications and implementations agree on which to support. Consistency with the other key types that support compression could also be nice.
