I agree with your sentiment. I have previously advocated that
Array.isArray should be transparent for proxies. My harmony-reflect
shim explicitly differs from the spec on this point because people
using the shim spontaneously reported this as the expected behaviour
and thought it was a bug that Array.isArray didn't work transparently
on proxies.
For reference https://github.com/tvcutsem/harmony-reflect/issues/13
As far as I can remember, the argument against making Array.isArray
transparent is that it's ad hoc and doesn't generalize to other types
/ type tests. My opinion is that array testing is fundamental to core
JS and is worth the exception.
Agreed. Author usability should trump language purity.

The subject is a SpiderMonkey bug.
Is that really desirable? Doesn’t it invalidate the Proxy’s role
as an interceptor?
