I dunno... Allowing the language to be selected like a video codec or image file format seems like a reasonable request.

There are three issues:

1) Language pluggable?

2) Spec-ed shader languages

3) Mandatory languages

The proposal was:

1) No

2 & 3) GL SL ES

Microsoft proposed:

1) Yes

2) GL SL ES

3) None

The perfectly reasonable compromise would have been:

1) Yes

2 & 3) GL SL ES

It may sound reasonable, but ultimately is against the universal spirit of the web, and thus should not be standardized. Your #1 should be No, because if it were Yes, we'd have a mess of mutually incompatible, vendor-specific, proprietary languages fragmenting 3D content on the web.

Mutually incompatible, vendor-specific, proprietary anything is an inevitability. #1 isn't about that. That's what #2 and #3 are about.

#1 is about planning for extensibility. Just look at the hackery with JS where lonely, otherwise ignored, strings are used for things like "use strict" and "use asm". Or where Microsoft added "conditional comments", which quite frankly, was essential to the development of Outlook Web Access, which basically gave us Ajax. Or all the absurd vendor prefixes on CSS tag names. Or one of 100 other little hacks that browser vendors have invented to try to innovate past the standard. Pushing pass the standard, by the way, is the only way forward. We've learned that lesson by now, so we should plan for extensibility.
