Considering (partial?) removal of OpenAlias support. Comment here if you use it.

With recent refactoring of invoices/payment requests, OpenAlias support is now partially broken.
Looking up an OpenAlias (name -> addr) works, however

• signing a payment request with an openalias is broken
  https://github.com/spesmilo/electrum/blob/eb39aa143b8112549a5f8156d8e3ee41034eac6a/electrum/wallet.py#L1772
• trying to pay a bip21 URI with embedded openalias name and signature is broken
  https://github.com/spesmilo/electrum/blob/eb39aa143b8112549a5f8156d8e3ee41034eac6a/electrum/util.py#L854
  https://github.com/spesmilo/electrum/blob/eb39aa143b8112549a5f8156d8e3ee41034eac6a/electrum/paymentrequest.py#L449

I am wondering whether this functionality is worth restoring/fixing.
We could remove the broken functionality;
or maybe we could strip OpenAlias support completely.

Do people actually use OpenAlias?
Do you use OpenAlias? What do you use it for?

If you want the project to keep supporting OpenAlias, please comment here.

Start by reading the OpenAlias-related paths in electrum/wallet.py:1772, electrum/util.py:854, and electrum/paymentrequest.py:449, then review the issue discussion about whether support should be fixed or removed. This issue is not ready for implementation until maintainers decide which direction to take and define the expected behavior.
