I doubt they would go away if there's an actual user of them, and if they did go away and someone who needed them came along, I expect they would be able to put them back, provided they were committed to maintaining it and turning it into something that was generally useful outside the context of a narrowly defined set of needs.
So my suggestion would be to try to make the loadable plugin system work for you and extending / improving it wherever you run into limitations. Feel free to hack around and propose patches to this effect. And for what it's worth, I also have some interest in seeing the loadable plugin system developed further as i have some ideas of how I would like to use it in the future, although this is still a ways out for me.
