I think the fix to this is worse than the problem.
Before this fix: A reappearing block nudges the player, only if the player is standing in that block.
After this fix: A reappearing block displaces and rotates the player, always. This is really disruptive since it "jerks" the camera maybe more than once per second at times.
Contrary to Xisuma's report, the nudging issue was also present before 1.14; I would encounter it fairly reliably while pillaring down in 1.13 (I learnt to just hold crouch while doing so). Xisuma's 1.13 video doesn't show that "reappearing blocks didn't used to nudge the player" because the video doesn't show reappearing blocks at all.
While reappearing blocks were mildly bothersome before 1.14.4, they did not frequently disrupt the player; you typically had to be pillaring down or running while insta-mining to be affected. The fix that is now in 1.14.4 disrupts the player for every single block that reappears.
