You are replacing a nice switch-case which handles all relevant resource
types with still having a switch-case + a separate if .. else if .. else if ...
(also taking patch 4/5 into account).
This does not help the readability of this code at all IMHO, so NACK
from me for this patch as well as for 4/5.
Regards,
Hans
