Before you correct me, please understand that you must use something
like growisofs to dynamically grow ISO9660 filesystems.  It's not
straight-forward and direct to do, as anyone who has run mkisofs knows,
it basically creates the table-of-contents first, then masters files
after it.  So if you add more, you either have to have another session,
or you block copy/move a lot of pre-mastered file so it can be "grown."

UDF just offers the other mode too, like Ext2, FAT, etc...

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
