Can somebody explain why pure numbers are allowed for username in

sudo useradd 123456789
is not rejected!
As is known, this leads to big problems if referring to such a user and
the username differs from the userid: should such a username be
interpreted as username or userid?
Thanks for each comment.
Kind regards
As you said using a pure number for userid can be diasterous But you
question needs to be answered by the creator of useradd.
I once created a useradd program with added functionality and I know
from first hand experience that are many pitfalls to get it to work
properly. Consider what happens if you have a userid that is the same
number as a userid.
