We found that the non-JavaScript tooling in the ecosystem was still nascent and wanted to do something about it friendlier to enterprise environments and security teams. We are using DIDKit as a base for adding this functionality to consumer-facing products, and hope others will find it convenient for this as well, so I look forward to giving updates on direct consumer use cases soon.
As per adoption by large tech/enterprises, we believe that as companies consolidate their data into warehouses, they will want (or need) to start sharing with partners, governments, and users in an auditable way. Some have compared Verifiable Credentials to the shipping container for verified data, and I don't think it's too off the mark.
We think these standards could also prove to be very straightforward ways to comply with data interoperability requirements imposed by laws like GDPR and CCPA. There will probably be more requirements in this direction if the US and EU decide to further regulate large tech companies.
