There is allways a way to do things ;-) Tweak a running
system itself for reload configuration is probably not the
best one.

As more as I think about what Fabio changed and what really
happens, I think it's just a missing API which splits the
ZCML action configuration and the running system into
different parts.

But since you're telling that reload patterns can work with 
this changes, I think this is good news.
