It would be beneficial. Right now there's no mechanism for third party to
bring in a replacement for PostGIS functions and get them selected in
postgis.backend GUC - the way it is done now is by providing a compile-time
list in postgis.so that will somehow delegate to one or other function.

If someone provides a javascript implementation for say
ST_DelaunayTriangles, they can't simply drop into it at all, apart from
renaming and wrapping it all into more layers and having strong
dependencies on creation order.
