After reading previous discussion:
http://help.lockergnome.com/linux/gentoo-dev-Deprecate-EAPIs--ftopict530567.html

Looks like preventing NEW commits from using eapi1 (via repoman) could
be done without major issues. This could even being done also for eapi2
as it's close enough to eapi3, but I don't have a strong opinion about
eapi2 deprecation (personally, I try to always use latest eapi if eclass
allows me to do so).

Any thoughts on this?

Thanks
