You have to pay for them anyway :P

No. In 'C' leadless at 0.15; leaded at 0.25; and BGA/capacitors at 0.5 (the
progression is done by some tool only);

Otherwise stick at the 'B' where substantially you can do everything at
0.25, can components at 0.5 and BGA at 1.0; also round everything on
a grid of 0.05 (that was done for imperial parts too; 'C' has both
metric and imperial).

I think that users needing the 'C' integration level will draw their own
library after talking with the manufacturer.
