For what it's worth, I was against it. Using /usr/lib/sse2 as we do now
works just fine as a solution to this problem. People without SSE2 at least
get a distribution that works for them, and even Qt 5 builds (except the
soon-to-be-packaged QtWebEngine module, sadly, unless/until something
happens at its upstream to fix the V8 non-portability) that work, albeit
slowly. LXQt should even work at an acceptable speed, given that they use
QtWidgets for their UI, which does not need the QML 2 interpreter or JIT (so
you don't get the non-JIT interpreter). And people with SSE2 get SSE2-
optimized .so binaries where it matters.
The only thing the duplication costs is some disk space, but that is the
price of portability.
