May I ask why?

Implementing the current ECMA behavior is a terrible idea because it features
non deterministic dispatch in case of ambiguous types.

Implementing the MS behavior is a disaster on itself as it's not documented and
lore say it's non deterministic too.

Also there is the issue that right now no major language ships with support for
it.

FX 4 is on beta and won't be ready for quite some time, so I see no reason to
implement now whatever we decide to.
