that is the point of confusion, which is still present in the
clarifications above - i see now, that the confusion is due to
redundancy (over-specifying, or repeating prescriptions for
cross-cutting concerns)

the most basic criteria (C0) implies that all important features
must work, given that the user allows libre scripts to execute -
stated inversely, some important features may be broken, if libre
scripts are not allowed to execute - C0 does not state either of
those interpretations explicitly; but it is logically implied by:

> C0: All important site functionality ... works correctly ...
> without running any nonfree software

so that extra qualifier in B0, reduces to a restatement of what
C0 already specifies (libre scripts may be required for full
functionality) - it seems that B0 adds only, that all scripts
must be freely licensed and labeled for machine parsing; but
adds nothing beyond C0, regarding expectations of functionality -
- A0 is clearly the point where full functionality does not
depend on scripting; so presumably, nothing of significance
would be lost if B0 were minimized, like so:

unless ... the intention of B0 is such that only "unimportant"
functionality may be broken, if scripting is disabled; but all
"important" functionality must work without scripting (a weaker
A0) - in that case i would clarify that in B0, to make it clear
why it mentions expected functionality at all

i believe that the intention is the former - it unclear
though, due to the vague concern with expected functionality
