You can use SF Symbols (https://developer.apple.com/design/human-interface-guideline...: “You can use a symbol to convey an object or concept wherever interface icons can appear, such as in navigation bars, toolbars, tab bars, context menus, and within text”). That would not use Apple’s emojis, but wouldn’t require you to create your own versions.
Source? Signal seems to be using the native emojis for reacts, and they don't seem to be having issues.

It wasn't removed, it was augmented.
So it makes sense for websites to force the rendering, so that everyone gets the same message.
Ideally, that pistol emoji mess shouldn't have started in the first place. It was clearly intended as a real gun, and variations in rendering shouldn't have impacted the meaning, but they did, and that's how we got there. If they wanted to off the real gun for a water pistol, they should have used a different code point, made keyboards only suggest that code point, and maybe censor the original pistol like they do swear words. No ambiguity.
This is a case of companies rendering 1F52B to something it is specifically not.
This was done on purpose.
