I wonder if the source map people could learn a thing or two from the debuginfo maintainers and vice versa.
Very cool to see so much work going on to make the web platform even more awesome - and in the open!
Stuff like this makes me believe open wins over closed in the end :)
This is a great endeavour. Recently I have been thinking about how to add syntax and metaprogramming extensions to programming languages without forking the compiler/interpreter. Source maps are needed there in order to have good editor support through e.g. an LSP server proxy. In researching it I was a bit let down I couldn't find too much research and specifications for the topic.
