Is it necessary to remove Emoji_Component?

[yisibl]

const emojiRegex = require('emoji-regex');
const text = `
🦰
 🏻
`;

const regex = emojiRegex();
for (const match of text.matchAll(regex)) {
  const emoji = match[0];
  console.log(`Matched sequence ${ emoji } — code points: ${ [...emoji].length }`);
}

Output:

Matched sequence 🦰 — code points: 1
Matched sequence 🏻 — code points: 1

Technically, I don't think these are Emoji. Maybe we should add an option to exclude these.
