We need dynamic binding to run old programs which were written for it.
We must keep it running forever for that reason.
Aside from that, I don't see a case where we really need to use it.

The 'e' command in the debugger needs to give access to the bindings
of the code being debugged -- even if that code uses lexical binding.
There are various ways to implement that.  How is it implemented now?
