The EAA has an article on the proposed changes:

"The FAA is proposing that an amateur builder fabricate a minimum of 20
percent of an aircraft and assemble a minimum of 20 percent of the
aircraft."

Mixing objective measures (e.g. percentages or fractions) without objective
definitions is absurd. Are those 20% numbers to be determined by weight, by
volume, by part count, by cost, by width, by height, by length, by labor
hours worked or avoided, or what?

They never knew what they wanted amateurs to prove and they still don't.
