[Public WebGL] specification/implementation cadence



I'd like to comment on some comments made in relation to future planning. The blow comment was by brandon a year ago (august 2015)

We're too deep into WebGL 2 to be distracted much with what WebGL Next looks like,
Avoiding that work in favor of focusing on a next gen API would be doing the WebGL community a huge disservice.

However, as a working group, we don't have bandwidth to even have effective debates on this right now. WebGL 2 must ship. I expect we'll get back around to WebGL-next later this year.
As such, I caution against investing work in designing anything ahead of the WG's availability. 

In various other discussions between 2012 and today this topic has come up: Let's drop everything and concentrate on WebGL 2, it being variously applied against WebGL 2.1, WebGL-next and extensions (of WebGL 1).

I don't think it's a good strategy to drop all future planning and specification work until one implementation has been finished (and not just specified, but also fully implemented).

There's probably too few people to simultaneously do specification work and implementation on the WG. But it isn't like this for any other standard and vendor group.

OpenGL has been specified at a cadence of 1-2 revisions of the API per year since OpenGL 3.0. It usually took vendors around half to a year to provide implementations, which means that at any point in time 1-2 OpenGL revisions where in spec phase and 1-2 implementations where in development by each vendor. Much the same is true for OpenGL ES.

WebGL 1 (which is the only currently usable version) is out of date by nearly 10 years, and WebGL 2 is out of date by nearly 5. It seems that while other standard bodies manage to output implementations and specs at a cadence of 1-2 per year, it takes the Web 5 years on average to advance by one.

Projecting this out to the future does scare me:
It's clear to me something has to change drastically on this trajectory. And the perpetual "Let's concentrate on the next thing" mantra doesn't seem to be working all that well (WebGL 2 was supposed to be available way sooner than end of this year).

I do appreciate that things do take time, but it just doesn't seem to me that pushing the next thing out till the last one has finished, is working out so great. The cycle usually is:
  1. Do A
  2. Don't plan B thing because A is soon finished
  3. A is delayed, putting strain on everybody
  4. Goto A
Seems to me to be a fairly well documented case of Waterfall planning breakdown and chronic resource shortage.
