Not. Like Environment Canada. Or most forecast models. Two hours is essentially USELESS.
I think people sometimes forget that Davis stations are bought by a whole spectrum of users. IME hobbyists, as largely represented in forums like this, are only a minority category of user.
Users overall do sometimes have applications where certainly 1-hour and occasionally 2-hour intervals are the only option that can be used. Say you're setting up weather logging as background information for some long-term ecological or environmental project in a relatively inaccessible location. You may be planning to visit the site only eg 2 or 3 times a year (especially if the site cannot easily be reached over the winter months) to do a data download to a laptop so 1-hour (100 days logging) and 2-hour (200 days) are often the only practical options.
And even if you're running a Connect for data connectivity then if you're using a 1-hour data plan (which is fairly common) then that's the granularity of your data, nothing more.
Remember that min/max temperatures, max wind gust etc are all recorded individually within an interval, so even 2-hour logging does generate a reasonably detailed picture of weather conditions over each 24-hour period.
