Actually we haven't decided whether SRI hash and the hash attribute is the preferred way forward (NixOS/rfcs#131), but hash looks nicer/DRYer than sha256 anyway. ¯_(ツ)_/¯

Okay, I was told to keep them unchanged (hash and vendorHash) in #227351 (comment) . So, people seem to have different opinions about what should be.

The TLDR is whichever the maintainers prefer, no reason to change it otherwise. Thanks for changing it back
