Sites like bitcoin.com have that feature and newbies might trust that site more than the official one.
By the way, https://live.blockcypher.com/ doesn't support bech32 addresses too.
There's no "official bitcoin site". If bitcoin.org tries to be as decentralized as possible they can't endorse any specific explorer or anything else. People should find their own explorers.
My favorites are btc.com and blocktrail.com, but I think btc.com is the best one. The design is simple and doesn't bloat my browser with useless stupid things.
Even if blockchain.info has the best design imo, I got tired of them waiting to give segwit address support so ditched them.
