It's a place where well-crafted pieces of code are revered. Sometimes social gatherings are held there to discuss the ways in which these things were put together.
On the other, at least it's still a reset option. That might sound silly at first, but I lost access to an old MS Live account that I had foolishly left on auto-login on my Xbox for years and eventually lost access to the old Hotmail account (yeah, I made this account a long time ago) it was tied to. No amount of offering to show that I was the credit card holder for the hundreds of dollars in games or anything would convince them it was my account.
For the people to whom their Instagram account is really important, this might be a nice option (even if it is rather invasive).
I worked at one data-heavy startup where things were on MySQL and even with a lot of consulting by Percona, eventually it just couldn't keep up with our needs, and the project was ported to PostgreSQL. I've worked on other projects that were less data intensive and MySQL worked fine though.
If given a choice, I'll take PostgreSQL any day, but I do understand that people are hesitant to change database whey they don't need to. If you are encountering trouble though, by all means, move on.
