The restrictions are put up with the intention of protecting the environment from getting broken by incompatibility that may be brought in by new packages, but the irony is that by sticking to these restrictions, they are broken already with respect to bug fixes and security fixes available with updates not being applied. They need to be educated that API and ABI compatibility will not be broken across minor releases of a single major version. It is essentially a confusion between update and upgrade, I feel. - rejy (rmc)
