I should have said some did methods “clearly have no relationship to a specific commercial platform”.  Of course “web” or “dns” is a technology but nobody could reasonably claim that you are preferencing some specific commercial interests ;)

I would argue that ALL DID methods have a relationship to a specific technology, but that technology is not necessarily a blockchain. The landscape of DID methods isn't really binary "with blockchain" or "without blockchain". It's much more diverse than that, and there are many different forms and combinations of "underlying technologies".

If the subject of the credential is a short lived thing like a trade consignment, maybe did:key or did:ipid is the ideal choice.  If you are a small business or citizen that wants to protect your privacy but also be able to prove your identity or entitlement as the subject of (say) a government issued credential, then perhaps did:kerri would work well.
