Don't subscribe in huge mass, if you are not going to use it within 2-3 month - regular map updates are expected in that period.
As for "glitch" in startup messages - the last one(s) is of importance for the end user. The whole loading is implemented in a way that it tests for all conditions (and complains if something is missing) during addition of each resource. That was easier for me to debug and implement. So, its OK
Note that you need raster maps only if you use corresponding client - current modRana or Poor Maps (old one).
