Make the 'Component Associations' UBO (on most devices) twice smaller -use the 'packed' layout and 'ivec2' in place of 'ivec4'.
This forces us to dynamically probe the 'Stride' - number of 4-byte entities that the UBO's 'ivec4' takes - and correct the already-constructed UniformBlockAssociation objects in case this turns out to be different than the expected 2, i.e. tightly-packed....
Introduce another Uniform Block Object. Now we can have much more vertex and fragment effects - up their default number to 100.
