No, if we're shoving retroactive changes into existing EAPIs (as would be done for making eapi a function), we could instead say "EAPI must be assigned to only once". That has *exactly* the same implications as having it as a function, except that the upgrade path is cleaner because there's no need for the horrid global scope die to work around existing package managers. > > Which is a "wait a year or more" thing...

Any sane package manager can, immediately upon a new EAPI being defined, do a stable release updated with minimal information about the new EAPI to enable it to show up as being there but not supported, even if full support needs a new major version and lots of ~arch testing time. -- Ciaran McCreesh
