Comment 2 for bug 1950095

"minimal potential for causing regressions" is a big claim given I had to fix regressions in later commits like 149b23c2b9697bc262c0af1934c7a3f6114d903f and 2b0369a5d1673d9e40f2af4db7677b040a26ee58. There might be more, that is just what I remember directly. It is certainly not the most complicated code in the world, but it's quite a bit of it as I was not trying for minimal, but instead maximized for forward and backward compat.

(Disclaimer: I am the upstream author of the patch set in question. Not involved enough with Ubuntu to know and/or predict if this qualifies or not for backport, so not commenting on that part. Pretty sure Debian would refuse if we tried including that in a stable update through).
