HAProxy's EoL dates are intentionally vague and not decided upfront. https://www.mail-archive.com/haproxy@formilux.org/msg41669.html

EOL dates are never precisely decided upfront, they're general guidance and are agreed upon with users. For example, 1.9 was supposed to die early in 2020-Q2 (possibly as early as April) and the last release was finally emitted on 31-July. Same goes for 1.6 which received updates till end of March 2020 despite being considered dead since end of previous year.

As such, the EOL statement has to be read this way: with the end of life expected to happen within the announced period, we're free to stop working on it during that period and you should not expect to see any update nor receive help during nor after that period if nobody explicitly asks. And it turns out that it works extremely well, encouraging smooth upgrades, and users not feeling guilty to ask about unmaintained setups "just in case".
