Yeah, it makes the 20 line limit redundant, and the only purpose of the
20 line limit was to support existing ebuilds in the wild.

Since the EAPI parsing behavior is optional for older EAPIs, package
managers can simply trigger a warning when they detect non-conformant
ebuilds in the wild, and eventually make it fatal after the community
has had sufficient warning.
