Bedrock: Mobs spawn too frequently, especially Wandering Trader

I usually play Minecraft Bedrock Edition on my phone and I have noticed over the past several years that the spawning mechanics seem to be seriously flawed (compared to Java edition): even with 'simulation distance' set to max, the amount of pigs, sheep, & cows which spawn around you as you move around is overwhelming for the performance.  I have even had times when trying to play with friends, they have commented, "why are there so many animals spawning everywhere? how can we get this to stop?"  The problem is even worse when traveling through the Nether, or anywhere at night because of the amount hostile creatures - especially the amount of magma cubes which spawn, for which I will need to bring multiple backup iron swords and shields to make sure I do not die.  However, the worst aspect of this spawn mechanic feature is the wandering trader.  They pop up all the time, hang around and take forever to despawn, and once one does (or if you decide to despawn it), another one will pop up within 5 or 10 minutes to continue going, "Hmm? Hmmm! Huak-Pffft!".  I can't even enjoy playing anymore because whenever I decide to join my world it's not long before they show up and I decide to quit.
