Labels are not useful as an identifier for LADSPA ports at all - there
are plugins out there that use the same label for several ports, for
example. Despite this there's code out there that attempts to use them
as such.

More generally there's been a lot of confusion and screw-up over
identification of plugins. The spec says to use the ID, which is
annoyingly centralized and limited. There are plugins in the wild with
conflicting IDs. Many people suggested using the library name and
plugin label as an identifier instead. Unfortunately this doesn't work,
there are packages of the same plugins with different library names, or
different distributions of plugins among libraries. I don't believe
there is a single correct way to refer to a LADSPA plugin that actually
works with all the plugins out there. Many people just have an
extremely small number of plugins (e.g. 2 or 3 of the most popular big
packages) and don't notice.

The index vs. symbol thing with LV2 is more to do with dynamicism and
versioning, though.
