The main reason contrib still has the alternate method is that PGXS
doesn't really work until after you've installed the core build.
For modules distributed separately from core, it doesn't seem that
exciting to be able to build using the contrib method.
Now, having said that, I'm personally interested in being able to build
pg_migrator against an uninstalled source tree, because I foresee
needing to do that for RPM packaging purposes. But I could easily patch
the makefiles if needed to make that happen. I don't think this case
should drive the choice of what's the default or common method.
