[swift-evolution] [swift-build-dev] Proposal: Package Manager Version Pinning

[Eloy Durán]

> 5. Given that many people agree there are two workflows (we ourselves had talked about this a lot when writing the proposal, but didn't put it in), we felt it makes sense to consider adding that as an explicit declaration *somewhere*.

What would you think of such a design?

Oooooooh, I like it.

Even though I would probably still pin/lock personally, I think this default combined with the explicit declaration strikes a perfect balance in trade-offs 👍
