Of course I would prefer “crc_hqx” to stay, because we use it at work. But I understand if you think it is not popular enough to justify maintaining it.

But I was more asking if the deprecation notice should point the way forward. This function is no longer recommended, so what should users do instead? Or at least explain why it is deprecated.

In my case, I may eventually write or resurrect a simple Python CRC implementation that shifts one bit at a time. But other people may desire a faster C implementation.
