It isn't mathematically possible to have Legendary members among the accounts created during 2019. Even if you created account on January 1st and have reached merit requirement, you would still be few month of activity short to reach Legendary activity requirement. And that's best case scenarion in case RNG gods like you you became Legendary with 775 activity.

Another think is worysome here, and that's the number of Sr Member accounts. Even if you made account on December 31st 2019, By now you would have enough activity to be Sr Member now, if you have met merit requirement of course. Based on that data, only 22 managed that, out of 1100+ accounts that got at least 1 merit. When you out that in the percentage, less than 2% of the accounts created during 2019 and received at least 1 merit are Sr Members now.

To me that shows that even something like that is a problem for huge majority of new users, so there is no real need to increase that. If numbers were opposite, if we have inflation of new users reaching high ranks, then I would think of this request as valid.
