867609 - (1JS) [meta] Retire JavaScript versions

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect, P2)

Description

Quoting Dave Herman bug 666399#c56 :
"The explicit versioning is Mozilla-specific, and is basically a failed
experiment; the overwhelming majority of the web doesn't use it. The
HTML5 zeitgeist and the "One JavaScript" (1JS) movement, meanwhile, have
moved away from opt-in versioning as an anti-pattern."

This bug is a meta bug. The process will be slow, require making sure that nothing breaks in the process. Dependent bugs will track that.

this doesn't depend on entire bug 1103158 but only bug 1083482 (legacy generator) and 1083470 (for-each)
no other legacy feature depends on JS version.

What is left to close this bug?

Nothing. We no longer support versions internally and since bug 1428745 the DOM script loader ignores versioned scripts.

Setting dependency accordingly
