Whatever happened to this multiarch effort?

[Nicholas D Steeves]

Following up on:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=824211#70

The LV2 multi-arch enabling thread stopped at the following:
https://lists.alioth.debian.org/pipermail/pkg-multimedia-maintainers/2014-January/036354.html

Did anyone ever follow-up with Robin Gareus or Alessio Treglia?  Does
LV2_PATH replace $LADSPA_PATH, and are there still any LADSPA V1
plugins in the archive?  Was it the potential of breaking the software
which didn't/doesn't use liblilv that caused this effort to stall?
Alternatively, I wonder if it was because it turned out to be such a
massive effort to patch a tonne of stuff...

Cheers,
Nicholas
