Not if plugin @sandbox compliance gets there first.

All I am suggesting is to do things in parallel rather than serially:
introduce the 'allow-plugins' option in tandem with ongoing plugin
compliance, rather than "plugin compliance first, allow-plugins
later".

For the reasons I outlined, in the short-term this is *very* useful
for products such as ours.  The assumption is that plugin compliance
will catch up sooner than (hypothetical) exploits become pervasive;
as Julian pointed out, the ball has been set in motion in that
direction.  If it doesn't (for some bizarre reason), authors can
simply avoid using the option.  (In that case, it probably means
plugin makers have gone bankrupt, so the option can be safely set to
'deprecated').

Additionally, neither of us seems to know for sure if Flash has access
to top.location...  If it turns out it doesn't, then your example is
not an issue at all.
