So long as this warning is only displayed within code part of Emacs
itself, there are no valid objections to such a change.

But you have instead elected to generate warnings whenever such files
are byte-compiled.  There exist many packages which do not enable
lexical binding, whose authors have studiously elected not to: most of
Drew Adams' for example.  So this is tantamount to punitive action
against their users, in the form of an unsightly warning each time such
packages are installed.
