"The defending team can push check and knock down their opponent within [20ft] of the net with reduced risk of drawing an interference penalty."
I'll see how this plays out, but if I'm understanding this correctly, I can already envision truculent/hip-check hitters abusing it to take people out of the play when they are nowhere near the puck. Anyone within 20 feet of the net waiting for a pass or getting into position is just going to be targeted.
"Community Feedback: Recent changes increased the chance of getting called for a penalty when Push Checking in front of the net. Defensemen want a way to clear the net, allowing for better defending in close proximity to the crease to prevent screens/deflections/tap ins."
Clear the front of the net. In close proximity. To me that's a few feet around the crease, not 20 feet.
I'd rather have stick/body tie ups improved.
Instead of lifting the stick way up in the air (using the "automatic penalty button"), you can engage and push off a player to move them out of screening position or pin their stick down to prevent a deflection. You can already "engage" with "net battle", though it is touchy. Make it easier to engage and allow follow ups from that position, either using the analog to "shove" a player (moving them a foot or two and ending the engaged state) or a "stick lift" which pins their stick for a couple of seconds before also ending the engaged state.
More thought may need to be put into it, but it accomplishes what is required without giving players free reign to take out attacking players.
