It is dangerous to step into a car since you can potentially drive
into a tree...

The functionality was there to begin with (prior to 1.5), I haven't
heard of anyone doing bad stuff which wasn't easily fixable, yet
removing this makes life harder for folks that depend on the original
behavior. The whole idea of request cycle listeners is to replace the
need for the One and True RequestCyle.

And I like the symmetry: onBeginRequest() happens right at the
beginning of the request—nothing happening before, onEndRequest()
happens right at the end of the request— nothing happening after.
