    Both IWD and wpa_supplicant provide options to disable the background scanning.

    For me setting the BSSID in NetworkManager was also useful to prevent it from scanning every 5 minutes to see if a better signal version of my network was found (for roaming purposes). This is the only way I found to play online games without constant lag spikes, although I aknowledge that this might be network adapter dependent.

    It's just a sarcastic way to state that Canonical has a long history of reinventing the wheel where they really should not have done that.

    Did you try tweaking the BandModifier5Ghz value in the config? https://jlk.fjfi.cvut.cz/arch/manpages/man/iwd.config.5

    it should tip the scales in favor of choosing 5Ghz networks

    I think (s)he's alluding to the previous projects where Ubuntu went their own way when a viable solution already existed.
    Some examples are:
    * Bzr
    * launchpad (was a leading OSS code hosting platform at a time, but the requirement of bzr killed it for many, and hosting your own was near impossible)
    * Unity (pre-8 was pretty awesome, and actually blazed some trails)
    * Upstart
    * Mir
    * Snap

    Honestly, it's not that much, but they often do them for what appears to be the wrong reasons.
    I also think their insistence in having a CLA that any contributor needs to sign killed many of their projects for them.

    Many access points ((nearly?) all enterprise ones, and some of the pro-sumer models) provide a hint (band steering) about preferring 5GHz over 2.4GHz, which addresses many use cases (and not just for IWD, but for other clients).

    And for IWD, there is the rank_5g_factor option which can address some other use cases.

    It should be noted that IWD already gives 5GHz some preference over 2.4GHz when things are approximately equivalent, but, of course, details always matter, which is why additional control is provided (via the rank_5g_factor option).

    It is a typo! It was the inverse!

    Yeah, 2020 is weird. Canonical is acting very strange.
