   Which of the two features that /etc/fstab is reset or that
/etc/fstab is cumbersome
  to modify after a chattr +i ?

  - /etc fstab reset at each boot:

     It is "built-in" casper since at least Edgy. It's true only for
CD/USB key boot
  (I think). I reset it at each ubuntu upgrade of my USB key !

    Once again: for normal boot it is not true.

  - unmodifiable /etc/fstab if you set it immutable

     I think it's clear.

           Hope this helps,
