As a user of just such an embedded system with Ubuntu, my personal bias is
to preserve this compatibility.  My understanding is that we would gain the
following in exchange for abandoning support for these low-end platforms:

- Some simplicity in glibc packaging (no more libc6-i686)

- The possibility of a small performance benefit for higher-end systems,
  though this is notoriously tricky to measure and we have no useful data

Personally, being able to run Ubuntu on low-end platforms seems worth more
to me.  µbuntu doesn't exist yet, and it's not clear to me that it would be
worthwhile to rebuild the entire archive for it.
