There's certainly no harm in asking, as you did. That's really the only way to determine something one way or another - after all, it's Admin's site, and his rules.
Don't be surprised if he comes back and says no, however. As Dan noted, there's a line that has to be drawn somewhere, just as there is with collectibles. In the past, the stance has kinda been that this is a trading card database, not a sports reference website - so while some reference items are intertwined with collecting (for example, players born in a certain state, or members of a Hall of Fame), not all things are necessary to enhance the appeal to trading card collectors.
I remember discussions in the past that revolved around having player uniform numbers displayed on their page (similar to Baseball Reference), draft year, teams played for, and I think another one that had to do with colleges that are listed on player pages (what if they didn't play sports, only got honorary degrees, etc.). What it boiled down to in the end was that this is a card database, and we leave a lot of the reference stuff to other sites while focusing only on the identifying and common bio information.
That's not to say that things haven't changed over time. And like a lot of things, there are people on both sides of the fence on the thought of adding more information to PIDs. Some share the view of not being a reference website, while others feel that the more information we have, the better off the site is. Personally, it doesn't affect me either way - what Admin says, goes, and I'm fine with that when it comes to this topic. Just want you to know why you're getting some of the feedback and why it's possible Admin may say "no".
Edited to add some clarification on certain sentences.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
