+1 for this. Armel at this point is clearly for a bit more legacy
devices, and Debian is one of the rare distros that support ARMv4.
Thus many embedded devices are likely to run Debian, and might run for
years and years. Any single digit percentage increase in performance
would make a switch to ARMv5 just a technological exercise for
builders, but a net loss for users.
The move to ARMv7 is going on strong, and armhf is here to provide the
performance. Raspberry Pi lives on the unfortunate middle ground that
would like to have ARMv6 with hard-float, but that's another story...
