Comment 6 for bug 1896506

If I remember correctly, the root issue is not really https://review.opendev.org/#/c/747857 which adds a config option specifically to mitigate the issue. It was originally added uconditionally with https://review.opendev.org/#/c/721799/ (and similar backports) seen as working fine with keepalived 1.x.
When it was reported to cause issues with some versions, this configuration option was added and backported so distributions can disable it per version and build

And of course all for a runtime detection check if you can get one, I do not remember the discussions around this patch but general opinion was it was not possible or at least not easy (remember checking the version is not enough for LTS versions)
