its a matter of what teams think is better.. lots of small performance upgrades, or bigger jumps less often.
The problem is that even some of these other teams that have been introducing small upgrades race-to-race will have fairly big upgrade packages in Spain. McLaren actually is supposed to have some upgrades in Spain, not sure where you hear they would not. Red Bull also has mentioned they have an upgrade, as well as Williams and Force India. Renault is said to have an upgrade too.
Toyota says they have a fairly big upgrade for Spain, and that is amazing considering Toyota has also been bringing small updates race-to-race.
BMW just seems to not have a very fast development pace this year with the new rules. Having a powerful supercomputer does not guarantee a team has the most advanced aerodynamics. A supercomputer is simply a tool; it is up to the engineers and aero guys to take full advantage of it.
It seems to me BMW has been relying too much on their supercomputer and has not been fast enough or clever enough to adapt to these new rules. Being clever with the new rules requires human ingenuity, not a supercomputer.
