3-terminal capacitors as bypass capacitor

instead of several bypass capacitors one cold use single 3-terminal capacitor.

In fact, Murata recommends them for exactly that application:

However you might find that, due to using more vias per capacitor, these parts take up more board space than you expect.

Also, you will be locked in to buying a fairly high-priced from Murata, rather than a commodity part you can shop around for.
