That's a theory, one inconsistent with the results of all other measures
to promote lexical binding that we have taken so far.

The mere existence of dynamically bound code is not a problem, and
nothing enjoins users to convert their code.  This is the sort of
fallacious thinking that leads people to propose draconian measures such
as the subject of this bug report.
