For the curious, below is a non-exhaustive list of promising tech clearly beneficial to developers and users, killed by Mozilla, on principle rather than technical merit:
1. WebSql - A web port of SqLite - arguably the world's second most used (and loved) tech. Instead, we have IndexedDb, which is such a damn hassle that a million wrappers exist to deal with it's shortcomings and complexity, including the tech presented in this blog post.
2. Nacl/PNacl - A precursor to WebAssembly which already had threads, SIMD, permissions, security ... figured out. By design, most Nacl code will run faster than webassembly, as Nacl's sandbox only excluded certain processor instructions deemed a security threat to it's sand-boxing model
3. HTML5 Storage: A file-system like storage for the browser! Killed by Mozilla...
But let's not kid ourselves: Mozilla hasn't been able to unilaterally kill things for years. We finally caved on H.264 in 2014, acceding to a patent-encumbered Web: https://andreasgal.com/2014/10/14/openh264-now-in-firefox/ The following year, we reluctantly added DRM to Firefox: https://blog.mozilla.org/blog/2015/05/12/update-on-digital-r....
Google was the only vendor that supported NaCl or the Filesystem APIs, and WebSQL similarly failed to gain traction outside of WebKit and Presto. If we were wrong in our assessments of those proposals, we weren't alone. And that's what killed them.
No one wants a monopoly in the browser space, and it seems like Mozilla has some other bone to pick with Google. As stated before, developers and web users come before Mozilla's philosophy, and many of the objections to Google's proposals don't seem to further that mission. Maybe some of it is in Mozilla's self preservation interests, I don't really know. But a lot of Google outrage seems feigned, and contrary to developer and user interest.
If you haven't noticed, most devs here haven't raised any technical objections, instead seem pleased with the offering, that's a hint in itself
I'm mainly and strongly objecting to this degree of external promotion for a Stage 1 proposal, along with positioning it, fait accompli, as part of "the Web."
