Do not overlook that electrolytics are variable capacitors, depending
on pretty much anything and therefore may increase noise in the
up-to-around-a-Hz domain.

Plastic film capacitors of releavant size do exist, for instance
Kemet's C44U series, but they are obviously huge and expensive.

Never attribute to malice what can adequately be explained by incompetence.
