No, I mean you may install handler only if you've found during config
parsing that it's needed somewhere.

Of course returning NGX_DECLINED will work too. And actually it
must be implemented anyway, as phase handlers can't be different
for different servers/locations, while you probably want perl
handlers to be configured on per-server and per-location basis.
