I'm using Jumpstart for several years now and the second 'dhcp' is 
not necessary.

Take a look at 'install-discovery' in yout boot image

   <path_to_image>/sbin/install-discovery

and search for 'TRY_DHCP'.

yes

Yes. Search for 'getbootargs' in 'install-discovery'

If you found this in the docs it's a bug. Booting with 'net:dhcp' does all
lookups with DHCP. bootparams is no longer needed.
