In case anyone is visiting soon, just sharing 3 quick updates with my fellow travelers.
1) RS says in his book you can go to the church next door to check your bag and "skip the line" to visit the basilica. That is no longer true. It's been converted to a self service locker storage. You can find more info on the storage facility here: https://www.stowyourbags.com/en/shop/venice/st-marks-square
1b) Bags up to 40x30x20 cm are allowed in. They have a sizing bin at the front.
2) Basilica was free with 3 Euro skip the line ticket you could purchase online. The basilica is no longer free and costs 3 Euro to enter. If you buy skip the line as well, it thus costs 6 Euros now.
3) As of Oct 2022, they are working on restorations of the middle section of the front facade. Just means you won't get the perfect pictures some of is hope for... no idea when the restoration will last for.
4) As of Oct 2022 they are handing out a mask for every person and STRONGLY urge you to wear it. Having said that, most of the tourists I saw ignored the masks and just stuffed it in their pockets.
