This has some information on the 2020 failure, but it is not what I remember reading.

There were core performance problems in the 2020 effort.

		ksh2020 is `v-` based, the repo I mentioned is an `u+` fork with backports from the failed attempt. Most notably, it doesn't change the build system. It's what Debian and Fedora use, so AT&T doesn't matter anymore. Real-world upstream is the repo I linked, which is maintained. All the 2020 drama is now obsolete.
