Since #commenting and #uncommenting uses to be less error-prone, I could imagine
a "dummy" translator that simply translates its subvolume to volume, and ignores
all other options given:

volume readahead
# type performance/read-ahead
    type features/dummy
  option page-size 65536
  option page-count 8
  subvolumes whatever
end-volume

volume writeback
  type performance/write-behind
  ...
  subvolumes readahead
end-volume

so "writeback" would be properly chained even if I decide to switch off 
readahead.

Anand, can we have a "dummy" "feature"? should be even shorter than "filter" ...

Vikas, I'm used to write my config files by hand...
