 Not perhaps, certainly :).

 I don't think there would be a noticeable penalty if the libraries were 
merged into one. They all link the same libraries according to ldd (except 
for some intra-dependencies), and they all together are less than 5M, so 
probably reading it all in one go may be in fact more efficient. But I cannot 
find something that would actually link libfwk [*], which is 3M, so at least 
merging the other 4 definitely makes sense even from performance point of 
view.

 I can't comment on other reasons why this might have been split though.

[*] Seriously, I can't find a thing. Is there actually something using the 
library?
