Because the point of unicode is to accurately depict every sort of writing regardless of format, not to make a neat table of every unique glyph. Fonts may want to render the two differently or treat them differently. Same reason why there’s a difference between an em dash and a quotation line mark
Same reason why unicode is full of random characters that only ever appear like thrice in some Russian coptic manuscript from the 3rd century - it’s about being able to depict something, not perceived usefulness
Also excuse my ignorance, but who’s Uriel? Because right now I just have the mental image of a very upset archangel which I’m guessing is not what you’re referring to. I mean it could be - I’m pretty sure unicode would fall under his domain of literature
Wordpress even has activitypub integration now! Hooray! Here’s hoping automattic do good on their word and bring it to their other projects like Tumblr
Also as much as I like gimp, it is unfortunately not that widely used due to super specialised and hard to use compared to the industry standard juggernaut that is adobe’s creative suite. You’re probably going to get laughed at in any professional industry if you suggest seriously using it.
