I realize the extreme difficulty it is for a small band of volunteers to get a project of this magnitude into a highly polished form.
That's true, but every project of any size dealing with a legacy architecture that's a decade old has problems going forward. It's not like Microsoft lacks for resources, yet they have had many problems and delays moving from XP to Vista. Apple just about lost it going from OS 9 to OS X. If you want a big well-funded open source example, Mozilla, almost disappeared during their transition from legacy Netscape code.
Every project has a hard time coping with end-of-life legacy code and major software transitions.
