Perhaps that would be an option for users who can't patch their
osmupdate binary and want to update their local OSM data even though a
new osmupdate release is not yet available.

osmupdate has a few command line parameters to restrict the kind of diff
files it uses to update local OSM files.

--hour
--day
        By default, osmupdate uses a combination of minutely, hourly
        and daily changefiles. If you want to limit these changefile
        categories, use one or two of these options and choose that
        category/ies you want to be used.

By specifying --hour (or additionally --day) on the command line,
processing is limited to hourly and daily diffs, which as we've seen
earlier on are still using the old format.

The data would no longer be up to date to the minute. Depending on the
use case, hourly updates may just be fine.

This is not meant as a permanent solution and should only be seen as an
option to get people going again that are stuck with their broken
pipeline. If you try this out, make sure to create a backup first.

Once a new osmupdate release is available, this workaround should be
removed asap.
