Poll: On ðe use of þorn and eþ in English, what would you do?

Ðis is a poll I made on Reddit's r/linguistics.

Based on ðe þesis I wrote, what would you do if þorn and eþ were added back to English?

1. Accept ðem into ðe English alphabet.
2. Recognize ðem as characters (possibly have ðem taught) but not include ðem in ðe alphabet.
Or
3. Ignore ðem and continue using "th".
