[...] (To anyone interested, there's a cross-post to the main Git list which Vitaly failed to mention: [1]. I think it could spark some interesting discussion.) As to the essence of the question, I think you blame GVFS for no real reason. While Microsoft is being Microsoft — their implementation of GVFS is written in .NET and *requires* Windows 10 (this one is beyond me), it's based on an open protocol [2] which basically assumes the presence of a RESTful HTTP endpoint at the "Git server side" and apparently designed to work well with the repository format the current stock Git uses which makes it implementable on both sides by anyone interested. The second hint I have is that the idea of fetching data lazily is being circulated among the Git developers for some time already, and something is really being done in this venue so you could check and see what's there [3, 4] and maybe trial it and help out those who works on this stuff. 1. https://public-inbox.org/git/CANxXvsMbpBOSRKaAi8iVUikfxtQp=kofZ60N0pHXs+R+q1k3_Q@xxxxxxxxxxxxxx/ 2. https://github.com/Microsoft/GVFS/blob/master/Protocol.md 3. https://public-inbox.org/git/?q=lazy+fetch 4. https://public-inbox.org/git/?q=partial+clone
