Please provide alternate APIs to see statistics that were removed from view, if reinstating them is off the table
One common use of the calendar UI was to see, if the user's consecutive days reset at some point in the past, what specific day(s) one didn't register a visit the site. Now, however, it's not possible to see that. While one can go back and calculate what was the first consecutive day they visited, they can no longer see if they didn't register visits on just a single day or multiple days, as well as any past cases where their counter got reset. It also would help Meta users out tremendously when responding to questions "why did my counter get reset [x] days ago even though I visited on all days": one can tell the user to open the calendar and see which day(s) didn't count (perhaps they visited on different UTC times, or perhaps they didn't have enough activity for a visit to be registered).
Also, as Martijn Pieters commented, moderators make use of the calendar to investigate voting fraud and for other moderation reasons.
Likewise, for the profile views, while it may be a vanity metric that not many people care about, as at least one user commented, some users do like seeing that. Removing it entirely without providing any alternate shuts it out entirely for those users. (The same thing also applies to the calendar: while it may not be responsive, the possibility for a curious user to see which days they themselves visited the site, or for a moderator to use it as part of an investigation, shouldn't be completely shut out.)
I understand that putting these on the page itself takes up space on the page and makes it harder to make the site completely responsive. However, if there's no way to reinstate them on the page without making it unclean, please provide an alternate method or API to be able to see them.
