Status on extensions for 1.0?

Hi Martin,

Would you mind giving us a status report on how the extension work is
coming?  Maybe a list of all the extensions and for each whether they're
good to go, in progress, broken, etc.

In reading some user critiques of Inkscape, sounds like some of the
extensions may be underutilized, so 1.0 may be a useful point to do some
selective curation?  Curious about if you already have plans underway
there.
