If a container should work, why does chroot not work? I don't
particularly care about running things side-by-side (as per the
enormous in-everyone's-face precedent of x86/x86-64), but why would
running an armv5tel guest in a chroot not "just work"?

It's far too easy to take the moral high ground when you aren't in
need of closed source software that you cannot just recompile.

Until a couple of months ago, the only Plex Media Server variant
available for ARM was armel (ARMv4 soft-float). It'll likely  be a
while before they provide an aarch64 PMS binary.

Additionally, it would be really handy to be able to use a big
aarch64 machine with tons of RAM for building 32-bit ARM packages.
Big compile jobs on the pitifully underpowered and under-RAM-ed
are increasingly painful, particularly the well known bloatware
such as web browsers (EL6 Firefox brings it's own GCC the build
process has to build first before using it to compile FF),
LibreOffice and others.
