I don't know what people expect.
All big linux distros are going to be quickly a target, because the people who like age verification laws like that hate the idea of free software.
Putting a dummy, useless age input, is a good way to comply maliciously, and can be easily reverted if these stupid laws ever get removed.
It wouldn't surprise me if obvious ways to bypass it appear a few seconds after the changes are validated.
The alternative is that these systems could be outawed in a lot of places, which would have a much more negative impact than an age field.
War is about knowing to take a hit to avoid defeat, sometimes.
