Is there any potential breakage to allow adduser --force-badname to

The only thing that immediately comes to mind is that of a MTA that
has to deliver mail for this user. For example, when cron runs a job
and needs to send the output to the owner of the cronjob, there will
be some ambiguity as to whether the part after the @ is part of the
username or in fact a domain name. This is especially true when
setting MAILTO in a crontab.
