As I understand it the end goal is bech32 addresses for Segwit
This is my understanding too. Bech32 addresses are called "native SegWit", and have a larger effect on transaction size than the more compatible 3-addresses.
Also looks like there are bech32 P2WSH addresses & bech32 P2WPKH addresses. Bloody confusing!
It took me long enough to remember Bech32, I'm not even trying to remember P2SH, P2WSH and P2WPKH. If I can't be bothered to remember, less tech savvy people won't care for sure.
Luckily, Bitcoin Core is quite conservative, and changes like this only happen about once per decade.
