Don't worry too much about that. It's just that the process of creating
LADSPA wasn't an easy one. When you have dozens of people of whom most
have developed their own plugin systems (some of them very complicated),
achieving any kind of compromise seemed pretty desparate.
The turning point with LADSPA was Richard Furse's determination. In the
end he was the one willing to do the actual work of writing a complete API
proposals along with documentation and examples. So it was the "show me
the code" attitude that again had the final say. :)
The situation really hasn't changed much. There's still numerous ways of
extending the API, but so far nothing has been done. The general consensus
has been (as I've interpreted it) that either convince Richard to adopt
your change, or create a new plugin standard. For instance MAIA -
http://www.linuxdj.com/maia/ - is one project that aimed to provide a more
complete plugin interface.

Yup. The reasoning behind LADSPA wasn't that we should only have one
plugin API and that the API should be simple. On the contrary, we just
realized we need to start from somewhere, even if it means we have to make
a compromise and leave the more complicated features to application
specific plugin APIs for the time being.
PS And remember that "show me the code" method is brutal
in its effectiveness. ;D
