Practical considerations when using a large number of capacitors in parallel
As DKNguyen pointed out it is important to "account for" or "manage" failures.
We put capacitor banks on the 28 VDC power bus of spacecraft all the time.
EVERY cap had its own fuse, so if the cap shorted out - which was the predominant failure mode - the fuse would blow and take the cap out of the circuit.
We were also concerned about partial shorts of a cap, so we broke the entire bank into 2, 3, or 4 sections and each section was fed with a relay so that we could disable that section of the cap bank if there was a partial short.
If you can , use a cap that has detailed specs on internal resistance and inductance and make a model on Spice (I use LT Spice) and check out the response across a wide frequency range - maybe up to 10 MHz.

Thanks  !!
