SNES Super Mario World - Clearing Levels Without Pressing A or B

The title of this post is exactly the name of an interesting playlist on YouTube.

The idea is: the player must complete the maximum amount of the 96 exits in the game without pressing A or B. Making a Tool-Assisted Speedrun is allowed and pretty much required in most levels (unless you're some god). Of course it's impossible to clear all of them, but the correct number of exits is still unknown.

Rules:
1) The buttons A and B are prohibited. You cannot press any of them, not even for a frame. You cannot either start the level with those buttons pressed.
2) You cannot start the level in a glitched state. For instance, you cannot start the level with an orb in the item reserve. However, you can start with Yoshi, with a cape and with a normal item in the inventory, even if you need to press A/B in previous levels.

Not discussed yet: the use of arbitrary code execution without pressing A or B on any joypad.

Table in progress: to add the difficulty and date.

TOTAL: 55 out of 96 exits, as of 2020/01/10.
                3 possible (as in we cannot state impossibility)
                1 hot        3 infeasible                   38 impossible

* SDS is almost possible, if only Yoshi could leave the floor at the beginning of the second room.
