remember that the OP was advocating that the distros should just drop any package that they think they need needs a patch that the upstream doesn't accept.
If the distros are going to do that, then they will not include cron, and any replacement for it had better ber drop-in compatible or you are going to seriously annoy a lot of sysadmins (especially since the uncooperative upstreams will change year to year, so packages will come and go)
not to mention the fact that this would also make these distros not linux, as one of the upstreams that just about every distro patches (with patches that are not acceptable upstream) is the kernel.
