bytes !

While I get the error/checksum capabilities Bech32 brings, any user would
prefer a 20 byte address with a checksum  over an address that would wrap
several lines !!


That's an unfair comparison. You're pasting a P2WSH address which contains
a 256-bit hash.

A P2WPKH address (which only contains a 160-bit hash, just like P2PKH and
P2SH) in Bech32 is only 42 characters, not 62.

Cheers,
