The problem is, without GLEP 55, EAPI isn't known before the ebuild is
sourced to generate metadata. If someone uses += anywhere that older
bash looks when sourcing for metadata generation (which is not just
global scope), the package manager won't know that the EAPI says that
bash-3.1 is required for sourcing until after it's already done the
sourcing, by which point it's too late.

The bash 3.0 transition was done before EAPIs came along, and was
handled by the old fashioned "wait for ages until we're absolutely sure
that everyone has bash 3.0 before continuing" method.
