Documentation error: --allow-freeform-uid not needed?

[Hauke Laging]

Hello,

I just noticed that it is possible to create UIDs without an email address 
without giving the option --allow-freeform-uid. The man page says:

--allow-freeform-uid
Disable  all  checks  on the form of the user ID while generating a new one. 
This option should only be used in very special environments as it does
not ensure the de-facto standard format of user IDs.

Google did not solve my confusion. This seems not to be related to --expert (I 
tried with --options /dev/null)
